Question

1.5:4=9:(2y+5)

Solve for y

Answer 1

y = 9.5

Explanation:

Express the ratios in fractional form, that is

`(1.5)/(4)` =
`(9)/(2y+5)` ( cross- multiply )

1.5(2y + 5) = 36 ( divide both sides by 1.5 )

2y + 5 = 24 ( subtract 5 from both sides )

2y = 19 ( divide both sides by 2 )

y =
`(19)/(2)` = 9.5
