Opposite angles in a parallelogram are congruent
So,
6x-10 = 2x + 50
Now solve like a normal equation
4x = 60
x = 15
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:


Therefore, the recommended slope for a sewer pipe is

Answer:
q = 177/13
Step-by-step explanation:
3q - 16q = 7 + 2(-89 – 3)
-13q = 7 + 2(-92)
-13q = 7 - 184
-13q = -177
q = (-177)/(-13)
q = 177/13
