Question

Stacy and Travis are rock climbing. Stacy's rope is 4 feet shorter than 3 times the lenght of Travis's rope. Stacy's rope is 23 feet long. Write and solve an equation to find the length t Travis' rope

Answer 1

23 = 3T - 4
Add 4 to each side
27 = 3T
Divide each side by 3
9 = T

Answer 2

The answer is 9 feet.

Explanation:

In order to determine the equation and its result, we have to define variables to describe the problem.

Defining:

L=length of the Stacy's rope

M=length of Travis's rope

Stacy's rope is 4 feet shorter that Travis's rope, so it means that we have to add more feet to her rope to equal to Travis's rope. Also, we have to compare the Stacy's rope with 3 times the length of Travis's rope, that it means, we have to multiply the length of Travis's rope by 3.

`L+4=3M\\L=23\\\\23+4=3M\\27=3M\\M=(27)/(3)\\ M=9`

Finally, the length of Travis's rope is 9 feet.
