A 143-m wire is cut into 3 pieces. The second piece is 3m longer than the first. The third is four-fifths as long as the first. How long is each piece? and tell me how you reached that solution
Let the first piece be of length x. So, the second and third pieces are what in terms of x? What is the sum of all three pieces? You now have an equation in terms of x and constants. Solve for x.
