Two Precalculus Problems
1.) . Note: To clarify, the "/" mark indicates fractions. Everything is a fraction except for 2x. I'm not certain how to solve this one, since I don't know exactly how to distribute fractions.
2.) Given the following two equations, solve for q:
Equation 1: 2pq=50 and Equation 2: p=(100+20q)/q
When combined, these equations should result in a quadratic equation. What I did first was substitute equation 2 for "p" in equation 1. However, I'm not certain if I solved the rest correctly from there. The quadratic equation that I found was x^2 + 40x+150=0. However, the resulting quantity was 43.452, which doesn't seem right because it is not a whole number. Please help me find the correct solution for q.
Thanks in advance. Your assistance is much appreciated.
