Answer:
B. 10
C. All real numbers.
Step-by-step explanation:
6 (2x-4) = 8(x + 2)
Distribute the numbers outside of the factors:
12x - 24 = 8x + 16
Subtract both sides by '8x'
12x - 8x - 24 = 8x - 8x + 16
4x - 24 = 16
Add '24' to both sides:
4x = 40
Divide both sides by 4:
x = 10. Therefore, B. 10 is the correct answer.
3(4p - 2) = -6(1 - 2p)
Distribute the numbers similarly to the example before:
12p - 6 = -6 + 12p
Subtract '12p' from both sides:
12p - 12p -6 = -6 + 12p - 12p
0 -6 = -6
Add '6' to both sides:
0 - 6 + 6 = -6 + 6
0 = 0
Therefore, the solution consists of all real numbers.

Answer:
[tex]4\sqrt{7}[/tex]
Step-by-step explanation:
Its a 45, 45, 90 triangle, which means that the hypotenuse is always the equals sides length by [tex]\sqrt{2}[/tex].
[tex](2\sqrt{14} )*\sqrt{2} = 4\sqrt{7}[/tex]
Answer:
[tex]4\sqrt{7}[/tex]
Step-by-step explanation:
The lines on the two sides of the triangle represent congruency (meaning that they both are worth the same value)
Use pythagorean theorem [tex]a^{2} + b^{2} = c^{2}[/tex]. a and b are both the same value
Square root to find c
The answer is then [tex]\sqrt{112}[/tex] now we need to simplify it further into radical form
Find the greatest set of numbers that include one perfect square and the other a normal number. These numbers should multiply to be 112
These numbers are 16 and 7
16 is the perfect square number because when you square root it, it is a clean number... 4!
The perfect square root always goes outside the radical and the other number (which is 7 in this case) always goes inside the radical

Answer:
A. 2.2
Step-by-step explanation:
The average rate of change between 2 x values is the total change of the y values (output values) divided by the change in the x values.Slope is special situation of that.
point 1 (x₁,y₁) → ( 2,7.5)
point 2 (x₂,y₂) → ( 18,42.5)
slope = 42.5 -7.5/18-2 =35 / 16 = 2.1875 ≈ 2.2

Estimate a 15% tip on a dinner bill of $57.86 by first rounding the bill amount to the nearest ten dollars.
Answer:
$70
Step-by-step explanation:
To add a tip, we must multiply the cost of the bill by 1.15. This will give us the total amount including the tip.
57.86 x 1.15 = 66.539
Because this is money, and it wants us to round to the nearest ten dollars, the cost would be $70. (66.539 is closer to 70 than it is to 60)
What is the value of X?
Answer:
The answer is 68 degrees.
Step-by-step explanation:
Angles of a triangle add up to 180 degrees. So you have to subtract 75 and 37 from 180. (180 - 75 - 37 = 68)
Answer:
C. 68°
Step-by-step explanation:
The angles in a triangle should all add up to 180°, so...
75°+37°+x°=180°
112°+x°=180°
x°=68°

Hope it works out !What I said 4 3/6 - 2 5/6
Answer:
1 2/3
Step-by-step explanation:
The denominators are the same, so we have to borrow from the 4
Borrow 1 in the form 6/6
3 + 6/6+3/6 - 2 5/6
3 9/6 - 2 5/6
1 4/6
Simplify the fraction by dividing the top and bottom by 2
1 2/3
Step-by-step explanation: To subtract mixed numbers, first subtract the fractions.
Notice here however that we have 3/6 - 5/6
which will give us a negative fraction.
Since this will cause us a lot of trouble, instead,
let's rewrite the first mixed number.
We can do this by thinking of 4 and 3/6 as 3 + 1 and 3/6
or 3 + 9/6 by changing 1 and 3/6 to an improper fraction.
So 4 and 3/6 can be written as 3 and 9/6.
So we have 3 and 9/6 - 2 and 5/6.
Now subtract the fractions.
9/6 - 5/6 is 4/6.
So we have 1 and 4/6 or 1 and 2/3.
As an improper fraction, the answer is 5/3.

Discussion
Urgent care centers are often open all hours, but may not be as fully equipped (or staffed) to provide the sort of emergency medicine that a fully-equipped hospital can provide. While a general- or nurse-practitioner can provide routine care, they will consult with specialists when expertise is needed in a specific area.
Various kinds of pregnancy centers can provide counseling and perhaps some medical services for planned or unplanned pregnancies.

It took Travis and Tony 40 minutes to skate 5 miles. The return trip took them 30 minutes. What was their average speed for the trip?
Answer:
[tex]\frac{1}{7}\,\,miles/minute[/tex]
Step-by-step explanation:
Given: Travis and Tony took 40 minutes to skate 5 miles and the return trip took them 30 minutes
To find: average speed for the trip
Solution:
Total distance = 5 + 5 = 10 miles
Total time = 40 + 30 = 70 minutes
So,
Average speed for the trip = Total distance/Total time = [tex]\frac{10}{70}=\frac{1}{7}[/tex] miles/minute
I n a polygon, there are 6 right angles and the remaining angles are all equal to 200 degrees each. Find the number of sides of the polygon.
(pls try to help me soon..)
Answer:
The polygon has a total of 15 sides
Step-by-step explanation:
Mathematically, the sum of the interior angles of a polygon can be calculated using the formula
(n-2) 180
Now there are 6 right angles. A right angle refers to 90 degrees. 6 right angles will be 6 * 90 = 540 degrees
Now the remaining number of angles in the polygon will be n-6 with each of this equal to 200 degrees each
The total amount of the remaining angles will be 200(n-6) = 200n-1200
Now adding all the interior angles will give the sum of 180(n-2)
180(n-2) = 200n -1200 + 540
180n -360 = 200n -660
200n -180n = 660-360
20n = 300
n = 300/20
n = 15
Between what two integers does square root of 160 lie ?
Answer:
It would be between 12 and 13.
Step-by-step explanation:
What we must do is find the square root of 160 and then round to the smallest number and the largest number, in this way we will know what integer that root would be, then we have to:
(160) ^ (1/2) = 12.65
If we round to the smallest number it would be 12 and if we round to the largest number it would be 13.
Which means that it would be between 12 and 13.

$10 a month fixed plus $0.10 for each message.
Variable:
m - number of text messages per month
Function:
c(m) - cost per month in dollars of Text-Pay Plan for m messages
Answer: c(m) = 0.10 m + 10
The Frequent text plan costs $20 for 0 messages (that's the fixed cost) and has a slope of (30 - 20)/200 = 1/20 = 0.05 dollars per message.
f(m) = 0.05 m + 20
How many text messages per month make these equal?
c(m) = f(m)
0.10 m + 10 = 0.05 m + 20
0.10 m - 0.05 m = 20 - 10
0.05 m = 10
m = 10/0.05 = 200
Check:
c(200) = .1(200)+10 = 20+10 = 30
f(200) = .05(200) + 20 = 10 + 20 = 30, good

plssss I need this now
Answer:
Model: y = 370 * (1.1)^t
Time for 600 cells: after about 5 hours
Step-by-step explanation:
The function that models an exponencial growth is:
y = Po * (1 + r)^t
Where y is the final value, Po is the inicial value, r is the rate and t is the time.
In this case, we have that Po = 370 and r = 10% = 0.1, so our model is:
y = 370 * 1.1^t
To find the time when the number of cells will be 600, we just need to use y = 600 and then calculate for t:
600 = 370 * 1.1^t
1.1^t = 600/370
1.1^t = 1.6216
log(1.1^t) = log(1.6216)
t * log(1.1) = log(1.6216)
t * 0.0953 = 0.4834
t = 0.4834 / 0.0953 = 5.0724 hours

which is the correct answer
Answer:
(a) (a² +3a -1)(a² -3a -1)
Step-by-step explanation:
The constant term of the product of the factors will be equal to the product of their constants. Since you want that product to be +1, the signs of the factor constants must be the same. That eliminates choices (c) and (d).
__
To tell which of choices (a) and (b) is correct, we can compute the squared term in their product. Let's do it in a generic way, with the constant (±1) being represented by "c".
We want the a² term in the product ...
(a² +3a +c)(a² -3a +c)
That term will be the result of multiplying both sets of first and last terms, and adding the product of the middle terms:
(a²·c) +(a²·c) -9a² = a²(2c-9)
So, we want the factor (2c-9) to be -11, which means c=-1, not +1.
The correct factorization of the given expression is ...
(a² +3a -1)(a² -3a -1) . . . . matches choice A
