Getting a good grasp on the fundamentals: Basic Math or GMAT
Hello Guys, I have been studying for the GMAT for a while now, but I am having trouble with the math section. I am not sure what is the best plan and which way I should focus my study time. I often study for hours, but I have trouble applying it to new GMAT questions. My question in this thread is: ...

Thank you for the reply, it makes much more sense now.
As for my question, I thought that if you squared a square root (in this case √3) that you would have to square everything else in the equation (-6)? So i presumed (falsey =( ) that √3x= -6^2 =3x=36 x=12.

Coordinate Plane Problem
I came across this question in a forum..... The angle made by the line \sqrt{3}x+y+6=0, with y-axis is 1. 60 degrees 2. 30 degrees 3. 45 degrees 4. 120 degrees 5. None of the above I was wondering, if I wanted to find the X intrecept, and made y equal to zero, the equation would become √3x=-6. If ...

Thank you for the quick reply,
If stem one gives 96 degrees, and 96 can only be the non-equal angle, then I cannot assume that it is the largest angle? If 96 was split could you not find the other angles?

Geometry DS Q (Iso Triangle)
In an isosceles triangle DEF, what is the measure of angle EDF? 1- Angle DEF is 96 degrees 2- Angle DFE is 42 degrees Answer: Statement 2 alone is sufficient, but state 1 alone is not sufficient. I will try to explain my logic as to why I though it was D (Each statement alone is sufficient). If you ...

I believe that the algebra confused me. I know from experience that 625 is 5^3, and eventually I figured out that 196 was 14^2. But I am not sure how I to apply those numbers into the formula. For example, I recognize that 196√3 is 14x14x3. However, since 625 is a cube, how can it be applied to th...

Thanks, I did not realize that this was a permutation problem. I assumed that becuase it would to be too time consuming to find all of the possible 4 letter words that the monkey wrote, that stem 2 would be insufficient.

Thanks! I had trouble understanding what the question wanted, and I did not realize that I should substitute 11 as q, which was my biggest fault. For arguements sake, because the question said that q can denote any element in Q set, could I assume that any positive integer is in Q set? Or does the 1...

Tetrahedron Lateral Surface Area
The lateral surface area, A, of a regular tetrahedron is related to the length of its edge a by the following formula A= √3a^2. What is the difference in the length of the edge of the tetrahedron with the area of 625√3 and the length of the edge of the tetrahedron with the area 196√3? A-3 B-9 ...

Dure, sorry for the late reply, but thanks!
I am curious, do you set up a proportion similar to the one you did in this problem for most ratio questions?

Set integer/multiple of Q
Q is a set of integers and 11 is in Q. Let q (small q) denote any element in the Q set. Is every positive multiple of 11 in Q? 1 q+11 is in Q 2 q-11 is in Q Answer: 1- Statement 1 is sufficient, but statment 2 is not sufficient Thanks! If anyone has time, please explain the answer thoroughly becuase...
