Question

a=1/2h(b1+b2) solve for b2. How on earth do I do this?

Answer 1

That appears to be one of those formulas for area. Isolate b2 using legal algebraic steps.

Answer 2

But how?

Answer 3

It matters whether you are talking about 1/2 (h) or 1/(2h). Whichis it?

Answer 4

The first one. 1/2 is a fraction.

Answer 5

There is many ways to go about isolating b2. Here is the path I would take. You do know that multiplying both sides of the equal sign by 2 would still maintain the equality.

2a= h(b1+b2) Did you follow that?

Answer 6

Yes, I understand that. But do I have to distribute now?

Answer 7

Now divide both sides by h. getting
(2a)/h = b1 + b2 Still with me?

Answer 8

Yes.. now do i just subtract b1?

Answer 9

I bet you can take it from there.

Answer 10

Yes, and be sure what you take away from one side take away from the other.

Answer 11

so its 2a/h -b1=b2?

Answer 12

As I said you could of worked it many different ways, including distributing the h etc.

Answer 13

I see you remembered, good job.

Answer 14

Alright, thank you so much!

Answer 15

No problem and you are welcome.
