Hey there! :)

Answer:

x = 12.

Step-by-step explanation:

Set the two proportions equal to each other:

\frac{5}{x}  = \frac{30}{72}

Cross multiply to solve for x:

5 · 72 = 30 · x

360 = 30x

Divide both sides by 30:

360/30 = 30x/30

12 = x.

Therefore, the value of 'x' in this proportion is 12.
