Answer:
x = 6
Step-by-step explanation:
(3x-2)/4 +1 =5
subtract 1 from each side
(3x-2)/4 +1 -1 =5-1
(3x-2)/4 =4
Multiply each side by 4
(3x-2)/4 *4 = 4*4
3x-2 = 16
Add 2 to each side
3x-2+2 = 16+2
3x = 18
Divide each side by 3
3x/3= 18/3
x = 6
Answer:
[tex]x = 6[/tex]
Step-by-step explanation:
[tex] \frac{3x - 2}{4} + 1 = 5 \\ \frac{3x - 2}{4} = 5 - 1 \\ \frac{3x - 2}{4} = 4 \\ 4 \times \frac{3x - 2}{4} = 4 \times 4 \\ 3x - 2 = 16 \\ 3x = 16 + 2 \\ 3x = 18 \\ \frac{3x}{3} = \frac{18}{3} \\ x = 6[/tex]

Tickets to a basketball game can be ordered online for a set price per ticket plus a $5.50 service fee. The total cost in
dollars for ordering 5 tickets is $108.00. Which linear function represents c, the total cost, when x tickets are ordered?
O c(x) = 5.50 + 20.50x
O c(x) = 5.50x + 20.50
Oc(x) = 5.50 +21.60x
O c(x) = 5.50x + 21.60
Answer: c the third option
Step-by-step explanation:
Answer:
Hope this helps!
Step-by-step explanation:
cost=flat fee+changing fee
flat fee=5.50
changing fee=cost per ticket times number of tickets
we know that 5 times cost per ticket=108
divide by 5
cost per ticket=21.6
c=number of tickets
total cost=5.5+21.6c
TC=21.6c+5.5

Jose drove 300 miles on his vacation. He drove an average of 1.5 times faster on the second 150 miles of his trop than he did on the first 150 miles of his trip. How much time did he spend driving? Let x = his speed on the first half of the trip.
Answer:
total time = 250/x
Step-by-step explanation:
Jose drove 300 miles on his vacation. He drove an average of 1.5 times faster on the second half of the trip. The time he spent driving can be calculated as follows.
The first half of the trip
distance = 150 miles
time = ?
speed = x
speed = distance/time
time = distance/speed
time = 150/x
The second half of the trip
distance = 150 miles
time = ?
speed = 1.5x
time = distance/speed
time = 150/1.5x
Total time travelled = 150/x + 150/1.5x
total time = 150/x + 100/x =150 + 100 /x = 250/x
total time = 250/x
Which expression is a sum of cubes?
-27a3b6+8a9b12
-9ab6 +9610
9ab6 + 8a12
27a3b8+8a9b12
Answer:
The first possible answer, -27a³b^6 + 8a^9b^12, is the sum of cubes.
Step-by-step explanation:
The middle two possible answers involve " a " with no exponent, so these could not be correct.
Looking at the first and fourth possible answers, we see that the first term of -27a3b6+8a9b12 is a perfect cube; it could be re-written as (-3ab²)³. The second term could be rewritten as (2a³b^4)³. So the first possible ansswer is the SUM of CUBES.

2. Solve the following equation for c. (5 points)
-8(1 + 4c) + 7c = -25 - 80
C=
Answer:
c=1
Step-by-step explanation:
Simplify both sides of the equation first.
−8(1+4c)+7c=−25−8c
(−8)(1)+(−8)(4c)+7c=−25+−8c
−8+−32c+7c=−25+−8c
(−32c+7c)+(−8)=−8c−25
−25c+−8=−8c−25
−25c−8=−8c−25
Add 8 to both sides.
−17c−8+8=−25+8
−17c=−17
Divide both sides by -17.
-17c/-17 = -17/-17
c=1

Jillian walked 0.5 miles before she started jogging at an average pace of 5 miles per hour. The equation d = 0.5 + 5t can be used to relate the total distance, d, in miles to the time, t, that Jillian spent jogging. What are the independent and dependent variables?
The independent variable is distance and the dependent variable is time.
The independent variable is time and the dependent variable is distance.
The independent variable is distance and the dependent variable is speed.
The independent variable is speed and the dependent variable is distance.
Answer:
The answer is option 2.
Step-by-step explanation:
In the question, the independent variable is time and dependent is distance. As the time changes, the distance will also change it means the distance depends on time.
For example,
[tex]d = 0.5 + 5t[/tex]
Let t = 1,
[tex]d = 0.5 + 5(1)[/tex]
[tex]d = 5.5 \: miles[/tex]
Let t = 5,
[tex]d = 0.5 + 5(5)[/tex]
[tex]d = 25.5 \: miles[/tex]
Therfore, as time increases, distance will also increase.
Answer:
B: The independent variable is time and the dependent variable is distance.

n is a positive integer
i) Explain why n(n+1) must be an even number?
ii) Explain why 2n-1 must be an odd number?
Answer:
Step-by-step explanation:
product of two consecutive numbers is always even.
n(n+1)
case 1
if n is odd,let n=2k+1,where k is an integer
n+1=2k+1+1=2k+2=2(k+1)
n(n+1)=(2k+1)[2(k+1)]=2(2k+1)(k+1)=even number.
case 2
if n is even,let n=2m,where m is an integer.
n+1=2m+1
n(n+1)=2m(2m+1)=even integer.
so in both cases n(n+1) is even.
James went shopping for a new watch. The original price was $150. It was marked down to $110. What is the percent of decrease?
Answer:
26.7% is the percent of decrease
Step-by-step explanation:
$150=100% price (starting og price)
110 =? or x (discounted price)
We need to find what is the decrease from 150 to 110 in percentage
Use ratios to solve:
$150:100%
$110:x (unknown)
Cross multiply to find x
150 times x= 150x, and 100x110 = 11000
= 150x=11000
Lets get x all by itself to fully solve. We have to divide to get x by itself:
= 150x/150=11000/150 (divide 150 both sides always)
= 73.3,
Now we subtract 73.3 from 100 to get the decrease percentage
100-73.3=26.7 which is the percent of decrease

The height of a ball dropped from the top of a 450-foot tall building can be described by the expression
450 - 16r, where
I represents the time, in seconds, after the ball is dropped.
What is the height of the object
4 seconds after it is dropped?
Answer:
The answer is 386 feet.
Step-by-step explanation:
This equation simply asks to plug in a value that gives you the final value of the height. 450 is the initial height, and r (or l) is referred to as the amount of seconds after the item is dropped. 16 is the constant value of feet that the ball drops within one second.
Therefore, by substituting 4 for r (or l) and multiplying it by 16, you will receive 64 feet in 4 seconds. Finally, you need to subtract this from 450 feet, giving you a final answer of 386 feet.
A fungus is infecting trees in a state park. Each week, the number of trees infected with the fungus doubles. Five weeks after the fungus is discovered, park rangers determine that 1,280 trees are infected.
Answer:
Week 1: 80
Week 2: 160
Week 3: 320
Week 4: 640
Week 5: 1280
Step-by-step explanation:
Week 5 there are 1280 infected trees, the infection numbers double weekly. Divide week 5 (1280) by 2 and you find week 4 (640) divide that by 2 and you find week 3 (320) divide that by 2 and you find week 2 (160) divide that by 2 and you find the first week (80)
The Number of infected trees are:
Week 1: 80
Week 2: 160
Week 3: 320
Week 4: 640
Week 5: 1280
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
In week 5, 1280 trees were infected.
As, Each week, the number of trees infected with the fungus doubles.
In week 4:
Number of trees infected = 1280 / 2 = 640
In week 3:
Number of trees infected = 640/ 2 = 320
In week 2:
Number of trees infected = 320 / 2 = 160
In week 1:
Number of trees infected = 160/ 2 = 80

GIVING OUT BRAINLIEST!! All sacks of sugar have the same weight. All sacks of flour also have the same weight, but not necessarily the same as the weight of the sacks of sugar. Suppose that two sacks of sugar together with three sacks of flour weigh no more than $40$ pounds, and that the weight of a sack of flour is no more than $6$ pounds more than the weight of two sacks of sugar. What is the largest possible weight (in pounds) of a sack of flour?
Answer:
flour = 11.5, sugar has to be equal to 2.75 pounds.
Step-by-step explanation:
your 2 inequalities are:
2x + 3y <= 40
y <= 2x + 6
the second equation can be shown as:
-2x + y <= 6
solve the equality portion of these 2 inequalities.
those are the following equations:
2x + 3y = 40
-2x + y = 6
add these equations together and solve for y to get
y = 11.5
that appears to be a break even point.
when y = 11.5, the first inequality is solved as follows:
2x + 3y <= 40
replace y with 11.5 and the inequality becomes:
2x + 34.5 <= 40
solve for x to get
x <= 2.75
when y = 11.5, the second inequality is solved as follows:
-2x + y <= 6
replace y with 11.5 and the inequality becomes:
-2x + 11.5 <= 6
solve for x to get x >= 2.75
this indicates that, when y = 11.5, x has to be equal to 2.75.
both constraints are satisfied.
Answer:
Let each sack of sugar weigh $s$ pounds and each sack of flour weigh $f$ pounds. Then from the given information, $2s + 3f \le 40$ and $f \le 2s + 6.$ Also, $s > 0$ and $f > 0.$ We graph these the intersection of these inequalities below.(document attached
We see that the largest possible value of $f$ occurs at the points where the lines $2s + 3f = 40$ and $f = 2s + 6$ intersect. Solving for $f,$ we find $f = \boxed{\frac{23}{2}}.$

if we multiply 11 and 11 then,it equals to 121
hope it helps...
Good luck on your assignment
Answer: Both numbers are -11.
Step-by-step explanation:
You can represent this using two equations, where the variables are x and y:
[tex]x + y = -22\\x * y = 121[/tex]
Then, solve the system using substitution by substituting y in the first equation into the second equation:
[tex]y = -22 - x\\ x * (-22 - x) = 121\\\\-x^2 - 22x - 121 = 0\\x^2 + 22x + 121 = 0\\[/tex]
Then, solve the quadratic equation by factoring it:
[tex](x+11)^2 = 0[/tex]
The only solution (or zero) to the equation is -11.
This means that both numbers are equal to -11.
-11 - 11 = -22
-11 * -11 = 121

Answer:
Yes it will.
Step-by-step explanation:
Imagine a circle. A full rotation is 360 degrees. So, that means you're going to be 90 degrees froma full rotation. That means that if you back track 90 degrees you're going to get to the same spot as when you go clockwise 270 degrees. The best way to think of it is having the hands of a clock start at 12.
