Answer:
The first piece = 20m
The second piece = 40m
The third pice = 8x = 160m
Step-by-step explanation:
Given:
Total length of wire = 220m
2nd piece = 2 times the 1st piece
3rd piece = 4 times the 2nd
To find:
The length of each of the piece
The wire was cut into 3:
1st piece + 2nd piece + 3rd piece = 220m
let the first length = x
2nd length = 2 (1st length) = 2(x)
2nd length = 2x
3rd length = 4(2nd piece) = 4(2x)
3rd length = 8x
The first piece = 20m
The second piece = 2x = 2(20) = 40m
The third pice = 8x = 8(20) = 160m
