Help!! Marcie wants to enclose her yard with a fence. Her yard is in the shape of a triangle attached to a rectangle. The area of this figure can be found by the formula A = (wh) + 0.5(bh). If Marcie wants the total area to be larger than a specified value, she can use the formula A (wh)+ 0.5(bh). Rewrite this formula to solve for b. Show all steps in your work.

bibby · Answer

A > (wh)+ 0.5(bh)

we're solving for b which means we want all terms with b in them alone. In this case we just want the bh alone.

How would you start?

anonymous · Answer

Divide hw from A

bibby · Answer

hw isn't being multiplied to anything so you can't divide it.

You can subtract wh from both sides though.

anonymous · Answer

Is this the answer: 
2(A-wh)/h=b

bibby · Answer

That's correct.

bibby · Answer

except it's not the equals sign. we're using " A > (wh)+ 0.5(bh)"

anonymous · Answer

So 2(a-wh)/h>b

bibby · Answer

I believe so.

anonymous · Answer

Do I simplify h

bibby · Answer

I don't think you can. That's the simplified form unless you wanna distribute the 2

anonymous · Answer

Okay I'll distribute it

bibby · Answer

Is it not accepting that answer?

anonymous · Answer

It's for book work. It's not plug into the computer

bibby · Answer

Ah, half the kids on here are in online school so I wasn't sure.
