Hi, A minor issue in the answer explanation to this problem. I am not copying out the entire explanation. If x and y are integers such that x < y < 0, what is x - y? (1) (x + y)(x - y) = 5 (2) xy = 6 Part of the explanation given is As you can see, the difference between squares grows as the s...

Hi, Not posting the diagram here cause I am not sure how to. The problem states that The length of minor arc AB is twice the length of minor arc BC and the length of major arc AC is three times the length of minor arc AB. What is the measure of angle BCA? It seems to me that the bolded portion must ...

Didn't realize the diagram was referring to a triangle. With all the calculations remaining the same as my previous post, angle...

Are x and y both positive? (1) 2x - 2y = 1 (2) x/y > 1 I quickly eliminated A and B since neither statement alone is sufficient but I am having a hard time setting up a methodical way to prove that together they are sufficient (the correct answer). Thanks! Arielle Hi Areille, I hope this can hel...

The ANS is (E) Aren't the statements contradicting each other?: .. What am I missing? From the question we know that: w/25 + 5/25 - w/25*5/25 = ? (DeMorgan's Law) In other words we just have to find the number of white balls in the box Statement 1 w/25*5/25 = 0 ... Thus w = 0 Statement 2 w/25 - 5/2...
