1. 1/a+1/b=1/c solve for c
2. I=nE/nr+R solve for n
Please show how you get the answer. I have tried to manipulate these formula's but can't seem to get it right.
Thanks-Melany

First add the fractions on the left handside getting: b+a/ab=1/c
then cross multiply:
cb+ac/ab=ab/ab then cancel out the a's and b's getting
2c=1. divide by 2 getting c=1/2. hope that helps!!!
second question is
subract R from both sides getting: I-R=nE.
Then divide both side by E getting I-R/E=n and your done!!!

A=a million/2bh initiate by potential of multiplying a million/2's reciprocal (opposite=2, turn the numbers) then divide each and every little thing by potential of two: 2A=bh (the a million/2 is canceled) to locate b divide each and every little thing by potential of h and you get: 2A/h=b

c=a+b
n cancels out...n can be anything
