30 girls , 12 were selected

40 boys, 16 were selected

We can simplify these down by finding the Greatest Common Factor in both girls and boys:

30:12 .... 15:6 .... 1 : 2.5 30/12 .... 15/6 .... 2.5

40:16 .... 20:8 .... 1 : 2.5 OR 40/16 .... 20/8 .... 2.5

They are equal ratios because their most simplified ratios/fractions are equivalent

Solve for x. <br><br> 45(15x+20)−7x=56(12x−24)+6

Liula [17]

Greetings!

Solve for x.
$45(15x+20)-7x=56(12x-24)+6$
Distribute the Parenthesis.
$675x+900-7x=56(12x-24)+6$
$675x+900-7x=672x-1344+6$
Combine Like Terms.
$668x+900=672x-1338$
Add 1338 to both sides.
$(668x+900)+1338=(672x-1338)+1338$
Subtract 668x from both sides.
$[(668x+900)+1338]-668x=[(672x-1338)+1338]-668x$
Simplify.
$900+1338=672x-668x$
$2238=4x$
Divide both sides by 4.
$(2238)/4=(4x)/4$
Simplify.
$559.5=x$
$x=559.5$

Hope this helps.
