Solve 2y - 5 over 3 = 4y - 1 over 2

ololo11 [35]

$\frac{2y - 5}{3} = \frac{4y - 1}{2}$
$3(4y - 1) = 2(2y - 5)$
$3(4y) - 3(1) = 2(2y) - 2(5)$
$12y - 3 = 4y - 10$
$8y - 3 = -10$
$8y = -7$
$\frac{8y}{8} = \frac{-7}{8}$
$y = -0.875$

The roof of the building shown below has a span of 48 feet. The rafters upon which the roof is laid are 30 feet long, including

anyanavicka [17]

Solution :

Given :

Span of the roof = 48 feet

Length of the rafter = 30 feet (including the 4 feet overhung)

So, for the 30 feet long rafter, 26 feet will be rafter length from the high point of the roof to the edge of the roof and 4 feet will be the roof overhung.

Therefore, the horizontal span per rafter is

$=\frac{48}{2}$
