What you do to one side of the equation you have to do to the other.
27,200/17=1,600

Answer:

28

Step-by-step explanation:

f(6) = -3 * 6 + 10 = -18 + 10 = -8

g(f(6)) = g(-8)

g(-8) = (-8)^{2} + 3 * (-8) - 12 = 64 - 24 - 12 = 64 - 36 = 28

Randy and Carla like to walk the path
Maksim231197 [3]
<h3>Answer:  18 miles</h3>

Reason:

The path is 2 miles and Randy walked it 13 times. He walked a total of 2*13 = 26 miles.

Carla walked the path 22 times, so she walked a total of 2*22 = 44 miles.

The difference of those results is 44-26 = 18 miles.

If you wanted to do the full calculation in one line, then it would be

2*22 - 2*13 = 18

or you could say

2*(22-13) = 18
