Question

Solve the proportion 40/z+1 = 15/6

Answer 1

z = 15

Explanation:

`(40)/(z + 1) = (15)/(6) \\`

Cross multiply

That's

`15(z + 1) = 40(6) \\ 15z + 15 = 240`

Send 15 to the right side of the equation

`15z = 240 - 15 \\ 15z = 225`

Divide both sides by 15

`(15z)/(15) = (225)/(15) \\`

We have the final answer as

z = 15
