Question

A 105-inch pipe is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece.
​

Answer 1

Answer:

$the \: length \: of \: the \: shorter \: piece = 10.5 - inch$

Step-by-step explanation:

$let \: the \: two \: numbers \: be : \\ x \: and \: y \\ x + y = \frac{105}{2} \\ 2(x + y) = 105 \\ if \: x \: = 4y \: \: then \\ 2(4y + y) = 105 \\ 10y = 105 \\ y = \frac{105}{10} \\ y = 10.5$
