So,
720 pt./hr.
2 pt. = 1 qt.
720/2 = 360
360 qt./hr.
Now, since there are 60 mins. in 1 hr., multiply the number by 60.
360(60) = 21600
720 pt./hr. = 21,600 qt./min.

<span>3x-9x+6=20-3x+4x
Combine like terms.
-6x+6=20+x
Bring x over to the left side.
-x -x
-7x+6=20
bring 6 to the right side.
-6 -6
-7x=14
Divide -7 on both sides to isolate x.
x= -2

ANSWER: x= -2</span>
For h(x) = -7x + 10, x =1
For r(x) = 4/5x+ 7 , x = -15
Step-by-step explanation:
in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values
So,
<u>h(x) = -7x + 10; h(x) = 3</u>
![h(x) = -7x+10\\3 = -7x+10\\3-10 = -7x+10-10\\-7 = -7x](https://tex.z-dn.net/?f=h%28x%29%20%3D%20-7x%2B10%5C%5C3%20%3D%20-7x%2B10%5C%5C3-10%20%3D%20-7x%2B10-10%5C%5C-7%20%3D%20-7x)
Dividing both sides by -7
![\frac{-7x}{-7} = \frac{-7}{-7}\\x = 1](https://tex.z-dn.net/?f=%5Cfrac%7B-7x%7D%7B-7%7D%20%3D%20%5Cfrac%7B-7%7D%7B-7%7D%5C%5Cx%20%3D%201)
<u>r(x) = 4/5x+7; r(x) = -5</u>
![r(x) = \frac{4}{5}x +7\\-5 = \frac{4}{5}x +7\\-5-7 = \frac{4}{5}x\\-12 = \frac{4}{5}x\\x = -12 * \frac{5}{4}\\x = -15](https://tex.z-dn.net/?f=r%28x%29%20%3D%20%5Cfrac%7B4%7D%7B5%7Dx%20%2B7%5C%5C-5%20%3D%20%5Cfrac%7B4%7D%7B5%7Dx%20%2B7%5C%5C-5-7%20%3D%20%5Cfrac%7B4%7D%7B5%7Dx%5C%5C-12%20%3D%20%5Cfrac%7B4%7D%7B5%7Dx%5C%5Cx%20%3D%20-12%20%2A%20%5Cfrac%7B5%7D%7B4%7D%5C%5Cx%20%3D%20-15)
