Question

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

Answer 1

Answer:

z = 15

Step-by-step explanation:

$\frac{40}{z + 1} = \frac{15}{6}$

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

$\frac{15z}{15} = \frac{225}{15}$

We have the final answer as

z = 15
