Question

A) Solve for b. A=1/2ab b) Evaluate when A=18 and a=3/2

Answer 1

a) A/(1/2)a =b

b) b = 24

Explanation:

a) Since everything is being multiplied on the right side you can just divide 1/2a to the other side that will leave b on the other side alone which is what you want

b) Just plug in the give numbers in the equation in part a) then do keep-change-flip then simplify then you should get 24 as the final answer.

Answer 2

A = 18 and a = 3/2

A = 1/2ab

18 = 1/2 x 3/2 x b

18 = 3/4 x b

6 = b/4

Therefore b = 24

Hope this helps you!
