I'm stuck on this question for my final. I need to solve for the lower case r in the equation. Ugh...last week of Algebra 2.

ugh.. I hate math

multiply both sides be R+r, then divide both side by I
it should be fairly easy after that.Yeah, well I'm gonna build my own lunar space lander! With blackjack aaaaannd Hookers! Actually, forget the space lander, and the blackjack. Ahhhh forget the whole thing!Comment

Not sure but the second line is the same as the first (Subtrat R from both sides, then divide both sides by r.
I get to [(E over I) - R) = r
From first line:
1. divide both sides by E (I/E = 1/(R+r)
2. Inverse both sides (E/I = R+r)
3. Subtract R from both sides ([E/I] - R = r)

Hey, that is a funny problem...
Don't forget to verify/mention that I cannot equal 0.Originally posted by gt40

Neither can R + r.Comment

The second line is me setting them up to be multiplied together...thats where I'm stuckOriginally posted by UmfriendWhy is it called tourist season, if we can't shoot at them?Comment

In that case, that is a good approach. You just need to realise that on the right hand side, you can scratch both R+r expressions.Originally posted by GT98Join MURCs Distributed Computing effort for Rosetta@Home and help fight Alzheimers, Cancer, Mad Cow disease and rising oil prices.

Actually, it is wrong how you did it. You write:
R+r.I = R+r.(E/[R+r]) and it should be:
(R+r).I = (R+r).[E/(R+r)]
Then, you will see how you can actually write this as
(R+r).I = E
Divide by I:
R+r = E/I
Subtract R:
r = (E/I) - RJoin MURCs Distributed Computing effort for Rosetta@Home and help fight Alzheimers, Cancer, Mad Cow disease and rising oil prices.

Whoa whoa!
Let's back up.
I don't see what they're looking for. They tell you, in essence:
2 * x = 2 * x, solve for x.
Are you certain you're including all the information, here?
Also, SOME people here need to remember that:
R + r * 2 is NOT the same as (R + r) * 2, not even remotely.The Internet - where men are men, women are men, and teenage girls are FBI agents!
