Question

Solve -9z >/= -72 CHECK YOUR ANSWER

Answer 1

z ≤ 8

Explanation:

-9z ≥ -72

Isolate the variable, z. Treat the ≥ as a equal sign, what you do to one side, you do to the other. Divide -9 from both sides. Note that when you divide a negative number, you will flip the sign:

(-9z)/-9 ≥ (-72)/-9

z ≤ (-72)/(-9)

z ≤ 8

z ≤ 8 is your answer.
