I am studying for the GRE by using practice books and taking practice exams. The answers are included for all questions, but not an explanation. I was able to deduce or otherwise help myself figure out the answer to most of the questions I missed, minus about 7. Unable to find answers with google or targeted math help sites, and knowing no one who is good at math nearby my place of residence, I thought it only reasonable to come here.
Given that these questions are elementary in nature (high-school, early college level), is it appropriate to ask these 7 or so questions in a single post, or should I create 7 threads, no matter how trivial may seem to be?
