Step-by-step explanation:
23x + 10y = 86
28x + 5y = 76
solve by elimination
multiply the top by -1 and the bottom by 2
-23x + -10y = -86
56x + 10y = 152
add them
33x = 66
x = 2
with x = 2 plug x into one of the equations
23x + 10y = 86
23(2) + 10y = 86
46 + 10y = 86
10y = 40
y = 4
x = 2 and y = 4 so

Letting x be the number of dvds, you could use the equation 8x + 12 = 84 to solve it, which would give you x = 9
We have been given that professional plumbers suggest that a sewer pipe should be sloped 0.25 inch for every foot.
Therefore, we can find the slope as:
![\text{Slope}=\frac{0.25\text{ inch}}{\text{1 foot}}=\frac{0.25\text{ inch}}{\text{12 inch}}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%7D%3D%5Cfrac%7B0.25%5Ctext%7B%20inch%7D%7D%7B%5Ctext%7B1%20foot%7D%7D%3D%5Cfrac%7B0.25%5Ctext%7B%20inch%7D%7D%7B%5Ctext%7B12%20inch%7D%7D)
![\text{Slope}=\frac{0.25}{12}=\frac{25}{1200}=\frac{1}{48}](https://tex.z-dn.net/?f=%5Ctext%7BSlope%7D%3D%5Cfrac%7B0.25%7D%7B12%7D%3D%5Cfrac%7B25%7D%7B1200%7D%3D%5Cfrac%7B1%7D%7B48%7D)
Therefore, the recommended slope for a sewer pipe is ![\frac{1}{48}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B48%7D)
