stupid question, and it doesn't pertain to me since i'm taking my test tomorrow anyhow --- but what is OG?

I know the answer, and I got the right answer, but I simply forgot some of the algebra that would allow me to get there. Can someone detailedly go through the algebra of this problem? I get the combining like terms part, and also get up to the part of getting a(b+c) + d(b+c) = 6. It's the just rest that where I get kind of hazy. And I'm writing this from memory, so I'm not quite sure if statement is really supposed to equal 6 or not. But I'm guessing that the actual numerical doesn't matter so much. What is the value of b+c? (1) ab+cd+ac+bd = 6 (2) a + d = 4

A store currently charges the same price for each towe that it sells. If the current price of each towel were to be increased by $1, 10 fewer of the towels could be bought for $120, excluding sales tax. What is the current price of each towel? (A) $1 (B) $2 © $3 (D) $4 (E) $12 I don't understand the phrase "10 fewer of the towels could be bought for $120" so this one completely threw me off. (Taken from PowerPrep CAT 2)

The attached JPEG corresponds to this question. If arc PQR above is a semicircle, what is the length of diameter PR? (1) a=4 (2) b=1 ANSWER: D (Either is sufficient) I kind of get it, but would like a thorough, clear explanation from all you smarties out there. Thanks!! :hmm:

aHa. geez. didn't think of sqrt2, sqrt3. thanks! i wish the frikkin test explanation itself would have said that.

sorry --- when i typed x^2, i was using the format i usually used in my TI-82 or TI-85 calculator, i mean x squared. sorry for the confusion. now do you see why I might be confused with the answer though?

3/2 as in the fraction 3 over 2? But statement 2 satisfies the necessity for (x^2) of being an integer and not a fraction, no?

Thanks for the response Nancy9!

If (x^2) + 5y=49, is y an integer? (1) 1 (2) (x^2) is an integer I say combined together, they are sufficient, .... ....since the first statement, if x were either 2 or 3, y would be an integer, but we're not told that x is an integer so the fact that (x^2) could be fraction is possible. so INSUFFICIENT ... but the second statement tells us that x is an integer. alone, that's INSUFFICIENT.. .. but combined, we're basically told that x can either be 2 or 3 which makes 49-(x^2) a multiple of 5. So I chose C. Please tell me why this way of solving the question is wrong since the answer is saying that it should be E.

I've been out of school for three years now, having graduated from Yale undergrad in 2001. I don't have much independant research under my belt since I went right into the work force (advertising) after school. But I've been considering going back to school for possibly a humanities PhD or Masters. I'm most interested in American Studies. I'm still kind of testing the waters and seeing if it's really for me. So, I've just taken my GRE this past September and I scored: V - 720 / 98th percentile Q - 660 / 59th percentile AW - 6.0 / 96th percentile (I know my math is atrocious:yuck: ) My GPA from Yale is a 3.31, in American Studies. Not so high, I know. :rolleyes: Does anyone out there know what American Studies programs look for for the GRE score of a candidate? And what else would come strongly into play?
