Answer:

$v = \dfrac{8}{a(y - 7)}$

Step-by-step explanation:

$y = \dfrac{8}{av} + 7$

Subtract 7 from both sides.

$y - 7 = \dfrac{8}{av}$

Multiply both sides by v.

$v(y - 7) = \dfrac{8}{a}$

Multiply both sides by 1/(y - 7).

$v = \dfrac{8}{a(y - 7)}$

Alina [70]

First add up the total parts in the ratio.
5 + 4 = 9

The girls has total of 4 parts, therefore we can just multiply the number of parts by the amount in each part
4 x 4 = 16
So there r 16 girls in the class
