Final answer:
To find the length of Travis' rope, set up the equation 23 = 3x - 4 and solve for x.
Step-by-step explanation:
To find the length of Travis' rope, we need to set up an equation.
Let 'x' be the length of Travis' rope.
According to the problem, Stacy's rope is 4 feet shorter than 3 times the length of Travis' rope.
So, we can set up the equation:
23 = 3x - 4
Add 4 to both sides to isolate 3x:
23 + 4 = 3x
27 = 3x
Divide both sides by 3 to solve for x:
x = 9
Therefore, the length of Travis' rope is 9 feet.
