Answer:
10.3 ft
Step-by-step explanation:
5.5/8 = x/15
multiply by 15
x=10.3 ft
14-2x=6+12x
14=6+10x
8=10x
0.8=x
Answer:
21 3/4 - 13 1/8 = 8 5/8 ft longer
Step-by-step explanation:
We subtract the blue rope from the green rope
21 3/4 - 13 1/8
We need to get a common denominator of 8
21 3/4*2/2 - 13 1/8
21 6/8 - 13 1/8
8 5/8
