Which is steeper: a road with a 12% grade or a road with a pitch of 1 in 8?
11Alexandr11 [23.1K]

Answer:

A road with a pitch of 1 in 8 is steeper.

Step-by-step explanation:

Let us convert these to the same units so that we can better compare them.

\frac{1}{8} = 0.125

0.125=12.5 %

As 12.5% is greater than 12%, the road with a pitch of 1 in 8 will be steeper.

Ganezh [65]

Answer:

D. 60

Step-by-step explanation:

4(3x + 3) = 5(x + 8)       12(4) + 12         5(4) + 40

12x + 12 = 5x + 40        48 + 12               20 + 40

-5x          -5x                   60                        60

7x + 12 = 40

 -12        -12

7x = 28

x = 4
