Sort each equation according to whether it has one solution; infinitely many solutions, or no solutions. 5 (x-2) = 5x - 7
-3(x-4) = -3x + 12
4(x+1) = 3x + 4
-2x (x-3) = 2x - 6
6(x+5) = 6x + 11

The physical fitness of an athlete is often measured by how much oxygen the athlete takes in (which is recorded in milliliters per kilogram, ml/kg). the mean maximum oxygen uptake for elite athletes has been found to be 60 with a standard deviation of 7.2. assume that the distribution is approximately normal.
