Respuesta :

3x+5x=25
x=25/8m
Length of the other piece = 3/8 x 5 = 1 7/8

Answer:

Length of pieces are 3.125 m and 1.875 m

Step-by-step explanation:

A piece of rope 5m long is cut into two pieces so that one piece is three fifths as long as the other.

Length of pieces be a and b.

Total length = 5 m

That is

            a + b = 5

One piece is three fifths as long as the other

              [tex]a=\frac{3}{5}b\\\\a=0.6b[/tex]

Substituting

             0.6 b + b = 5

                  1.6 b = 5

                      b = 3.125 m

            a = 0.6 x 3.125 = 1.875 m

Length of pieces are 3.125 m and 1.875 m
