3x-3y+2z=11
3x+y-3z=-11
15x-y-2z=0

If you are looking to solve the system of equations your answer would be:

x = 1/2, y = -1/2, z = 4

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

answer is d-29

step-by-step explanation:
