Hello all! I have a bachelor's of science, and I started studying for the GRE to get into grad school, but I realized my basic math skills are very rusty. I've been out of college for 4 years, and it's been even longer since I've done any "real" math. Looking back, I barely passed physics, and I want to be better than that! I'm starting with a review of algebra and hoping to improve from there. I at least want to get back to a point where I'm comfortable with conversions and ratios of moles needed for chemistry calculations; I'm also aiming for a job in a research lab.

Well then... I guess I'll get started here before settling down into the algebra forum.

I'm looking at basic word problems right now:

Find the measure of an angle whose supplement measures 7 times the measure of its complement.

I think 7 times the supplement = 7(180 - x)

And the complement = (90 - x)

But I'm not sure how to make an equation out of it.

Also, how do you guys generate those very clean-looking math images?
