Answer :
Answer:
the length of the longer piece of cable is 24 ft
Step-by-step explanation:
shor piece = s
Long piesce = s+9
s + s+9= 39
2s = 30
s = 15
short = 15
15 +9 = 24
long = 24
15+24 = 39
Answer:
24 feets
Step-by-step explanation:
let the shorter cable be x feets
so the longer cable will be 9 plus the shorter cable which is (9 + x) feets
- Total length = Longer cable + shorter cable
- 39 = (9 + x) + x
- 39 = 9 + 2x
- 2x = 39 - 9
- 2x = 30
[tex]x \: = \: \frac{30}{2} \\ x = 15feets[/tex]
- But the longer cable is (9 + x)
- So longer cable = 9 + 15
- Longer cabl = 24 feets
