Answer:
Step-by-step explanation:
So for this, replace the x variable with 12 to solve:
<span>A=1/2(a+b)h for h.
First, you need to get rid of 1/2, so divide both sides by 1/2.
A/(1/2) = (a + b)h
You can simplify the </span>A/(1/2) by multiplying by the reciprocal of 1/2, so 2/1.
2A = (a + b)h
Now divide both sides by (a+b).
2A/(a+b) = h
4/7
Subtract 15 from 35 to get the remaining number of pens. 20 red pens are in the box. Divide 20 by 35 and reduce to get 4/7.
