Question 364493
a pipe is fifty-six feet long. it is to be cut into two pieces with one piece two-fifths as long as the other. find the length of each piece.\
.
Let x = length of one piece
then
(2/5)x = length of second piece
.
x + (2/5)x = 56
multiply both sides by 5:
5x + 2x = 5*56
7x = 5*56
x = (5*56)/7
x = 5*8
x = 40 feet (one piece)
.
Second piece:
(2/5)x = (2/5)40 = 16 feet
