Corresponding sides must be proportional and corresponding angles are congruent.

Answer:
Step-by-step explanation:
x + y = 27
We know that there are 5 less girls that boys, so:
x + (x-5) = 27
x + x - 5 = 27
Solve for x:
2x - 5 = 27
2x = 32
x = 16 boys
y = 11 girls
tell me if you see anything wrong
3/4 - 1/8 = 6/8 - 1/8 = 5/8...so 5/8 = 10 gallons
(5/8) / 10 = 1 / x
cross multiply
(5/8)(x) = (10)(1)
5/8x = 10
x = 10 * 8/5
x = 80/5 = 16 <== so it would take 16 gallons to fill the tank
The answer i think it is, is C
