Answer:
12x^2 - 5x - 3
Step-by-step explanation:
Answer:
This ratio means for every boy there are two girls.
There are twice as many girls as there are boys. Backwards, it's there are half as many boys as there are girl.

5/10 = 1/2
Both sides on the unsimplified ratio are division by 5. When done, it became 1/2.

F________G_______H_______I
we know that
FI=FG+GH+HI-----> solve for GH
GH=FI-FG-HI
FI=7 units
FG=2 units
HI=1 unit
substitute
GH=7-2-1-----> GH=4 units
the answer is
GH=4 units
