A rope is 9cm longer than a wire. A ribbon is 8 times as the wire. The total length of the rope, wire and string is 209cm. How much longer is the ribbon than the rope?
Answers
Answer:
The ribbon is 131 cm longer
Step-by-step explanation:
Let the length of the wire be x
The length of the rope = x + 9
The length of the ribbon = 8x
Total length = 209 cm
ATQ,
x + x + 9 + 8x = 209 cm
10x + 9 = 209 cm
10x = 209 - 9
10x = 200
x = 200/10
x = 20 cm
Length of rope = 20 + 9 = 29cm
Length of ribbon = 20 * 8 = 160cm
Hence the ribbon is 160 - 29 = 131 cm longer than the rope
Answer:
131 cm
Step-by-step explanation:
The ribbon is 131 cm longer.
