Given a = 1/2(b1 + b2)h, solve for h.

The answer is h = 2A/(b1 + b2).

In order to find this, use all the methods for solving typically used in these types of equations. See the below example.

A = 1/2(b1 + b2)h ---> Multiply both sides by 2.

2A = (b1 + b2)h > Divide both sides by (b1 + b2)

2A/(b1 + b2) = h

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

location: point 0

step-by-step explanation:

well, -8 to 10 on a number line is 18 spaces.

1/9 of 18 is 2.

so, 4/9 of 18 must be 8.

8 spaces from -8 (a) is 0.

so, 4/9 of the way from -8 to 10 is 0!
