Solve A=h/2(b1 + b2) for h. Is this like the one before? We are a bit confused.

Question

turingtest · Answer

this is$$A=\frac{h}{2}(b_1+b_2)$$right?

anonymous · Answer

Yes, we didn't know how to type it out like on the paper.

jhonyy9 · Answer

h=2A/(b1 +b2)

turingtest · Answer

1)multiply both sides by 2
2) divide both sides by (b1+b2)
don't worry about the (b1+b2) it acts like a regular number x, as you can see in jhonyy's answer

anonymous · Answer

Okay, we'll try to write this out and show you how we did it just to double check.

anonymous · Answer

2A = h (b1+b2) <= Times by 2
2A = h (b1+b2)
/(b1+b2)
=
2A/(b1=b2) = h
?

turingtest · Answer

you have an equals sign where there should be a plus sign, but other than that, looks good

anonymous · Answer

So, there should be a plus sign between the 2A and the h?

turingtest · Answer

1) multiply both sides by 2$$2(A)=2\frac{h}{2}(b_1+b_2)\to 2A=h(b_1+b_2)$$2) divide both sides by (b1+b2)$$\frac{2A}{(b_1+b_2)}=\frac{h(b_1+b_2)}{(b_1+b_2)}=h$$

Oh, okay. That looks a lot clearer. Thank you.
