Simple Algebra problem that is killing me!! 1. The problem statement, all variables and given/known data From the set of equations below, involving the unknowns p, q, r, and t, find the values of t / r. (Use the correct number of significant figures.) p = 7q pr = qs 0.5pr^2 + 0.5qs^2 = 0.5qt^2 2. Relevant equations ~ 3. The attempt at a solution I have been working on this problem for some time now. I have tried dividing all the terms by r^2 and seting (t/r)=x just to simplify the answer. I have come up with 7.5 and -7.5 but it says these answers are incorrect.
