A 64-inch board is cut into three pieces so that the second piece is twice as long as the first piece, and the third
Dafna1 [17]
<h3>Answer:  40 inches</h3>

==========================================================

Explanation:

  • x = first piece
  • 2x = second piece, since its twice as long as the first
  • 5x = third piece, since its five time as long as the first

x is some positive real number, and the units of each are in inches.

Add up the smaller pieces and we should get 64 inches back again

x+2x+5x = 64

8x = 64

x = 64/8

x = 8

The first piece is 8 inches long.

2x = 2*8 = 16 is the length of the second piece (in inches)

The third piece is 40 inches because 5x = 5*8 = 40

--------

Summary:

first = 8 inches

second = 16 inches

third = 40 inches

Check: 8+16+40 = 64, which confirms the answer
