Solve for a.
ab + c = d.
Answer:
a = (d-c)/b
Step-by-step explanation:
ab + c = d
ab = d -c
a = (d-c)/b
Answer: a = d - c/b
Explanation: To get a by itself, we first subtract c from both sides.
So we have ab = d - c.
Now divide both sides by b to get a = d - c/b.

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
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

Jason enjoys watching the squirrels in his neighborhood park. They eat the red oak acorns. After the city removed 4 diseased red oak trees, the population of squirrels decreased from 105 to 98 in one year. If the population continues to decline at the same rate, how many squirrels will live in the park in 15 years? First, calculate the rate of decay by subtracting the two populations and dividing the difference by the initial population. Then, use the formula A=a0ekt
a. 0 squirrels
b. 95 squirrels
c 81 squirrels
d 34 squirrels
Answer:
0 squirrels
Step-by-step explanation:
If you subtract 98 from 105 then you get 7. That means that 7 squirrels will be lost per year. If you then multiply 7 by 15 (15 is the amount of years) then you get 105 and since there were 105 to start off with, there will be no squirrels left after 15 years.
Answer:
34 Squirrels
Step-by-step explanation:
7\ 105 ~0.07
A=Aoe^kt
A=98e^(-0.07•15)
A=98e^-.05
A=34.3~ 34 Squirrels

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 $f = \boxed{\frac{23}{2}}.$

The table that shows the relationship between h, the number of hours John’s brother works, and c, the total cost of the project is third table.
What is multiplication?Multiplication is mathematical arithmetic operation. It is also a process of adding same types of expression to some number of times.
Example - 2 × 3 means 2 is added three times or 3 is added 2 times.
Given that John paid $485 to build a deck.
And he will pay $25 per hour to his brother for building the deck.
one hour of work costs John $25 + $485 .
Total cost of building deck = $25 × h number of hours + $485
3 hour of work costs $25 × 3 = $75 + $485 = $560
8 hour of work costs = $25 × 8 = $200 + $485 = $685
12 hour of work costs = $25 × 12 = $300 + $485 = $785
Therefore, the third table suggests the total cost of work.

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

Find the equation of the line that is perpendicular to y = 1/4x – 2 and passes though the point (5, –2). A) y = –1/4x + 18 B) y = –1/4x – 22 C) y = –4x + 18 D) y = –4x – 22
Since our line is perpendicular to this line, the slope of
our line is the negative reciprocal of 1/4, which is -4/1.
Remember, negative reciprocal is just a fancy way
of saying flip the fraction and change the sign.
So the slope of our line is -4/1 and we use this slope along
with our given point to write the equation of our line.
Start with the point-slope formula.
Y - y1 = m(x - x1).
~Substitute
Y - -2 = -4/1(x - 5).
Minus a negative is plus a positive.
Y + 2 = -4/1x + 20.
Subtract 2 from both sides.
Y = -4/1x + 18
So, our answer is C.

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.

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 two numbers add to -22 and multiply to 121?
-11 and -11 are the two numbers that adds to -22 and multiply to 121
If we add 11 and 11 then it equals to -22.
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
