Answer:
Step-by-step explanation:
4x + 6 + 3x + 21 = 8x + 7
7x + 27 = 8x + 7
-x + 27 = 7
-x = -20
x = 20
m<3= 8(20) + 7
160 + 7 = 167
m<1= 4(20) + 6 = 80 + 6 = 86
m<2= 3(20) + 21 = 60 + 21 = 81

Answer:
Step-by-step explanation:
4=y/8+1
rewrite equation
y/8 + 1 = 4
move all terms not containing y to the right of the equation
y/8 = 3
multiply both sides of the equation by 8
8 x y/8 = 8 x 3
simplify both sides of the equation.
y = 24
Horizontal distance = 48'
difference in elevation = 18"-6" = 12" = 1'
Slope of the sewer line = rise/run = 1/48 = 0.0208 = 2.08%
