Question 362275
a wire is 224cm long is cut into three pieces the  first is twice as long as the second the third is one-half as long as the second how long is the second piece?
..
let second be x cm
first = 2x
third = x/2
..
x+2x+(x/2)=5x/2
7x/2=224
multiply by 2
(7x/2)*2 = 224*2
5x=448
/7
x=64
x=64 cm the second part
first part = 2x = 64*2=128 cm
third part = x/2 = 64/2=32 cm
