Problema Solution

A 143 meter wire is cut into three pieces. The second is 3 meters longer than the first. The third is four-fifths as long as the first. How long is each piece?

Answer provided by our tutors

Let x, y, and z stand for the 1st, 2nd and 3rd pieces of the wire. We can write:


x+y+z=143

y=x+3

z=(4/5)x


Using Algebrator to solve for x, y, and z, we get:

x=50 m

y=53 m

z=40 m
