Answer:
The length of the longer piece is 35 feet.
Step-by-step explanation:
Let the length of the longer piece is x
Hence, length of the shorter piece is 3x
Now, the length of the rope is 140 ft. Thus, we have the equation
[tex]x+3x=140[/tex]
Add the like terms. [tex]x+3x=4x[/tex]
[tex]4x=140[/tex]
Divide both sides by 4
[tex]x=35[/tex]
Therefore, the length of the longer piece is 35 feet.
