Question

Happy Halloween! My eighth grader needs some help with literal equations. Done several of them already, but stuck on this one. Thank you all so much!

Answer 1

a=hb ₁/2 + hb₂/2

Step-by-step explanation

Answer 2

(2A/h) - b1 = b2

Explanation:

A = 1/2h (b1 + b2)

1. Multiply by 2 on both sides

2A = h (b1 + b2)

2. Divide by h on both sides

2A/h = b1 + b2

3. Subtract b1 on both sides

(2A/h) - b1 = b2
