Answer:
The answer is 9 feet.
Step-by-step 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.
[tex]L+4=3M\\L=23\\\\23+4=3M\\27=3M\\M=\frac{27}{3}\\ M=9[/tex]
Finally, the length of Travis's rope is 9 feet.
