Answer:
z = 4
Step-by-step explanation:
18z = 72 (First divide by 18 to isolate z, the exponent)
To check our answer, lets plug 4 back into the equation
18(4)
72
72 = 72
60 gallons
We can create a ratio for this. If we consider 2 as the 1 in the ratio, we have a ratio of 1 : 2.5. Therefore, we just need to multiply 24 by 2.5, which equals 60.
the answer is -9
