Answer:
2.89
Step-by-step explanation:
Note the equal sign, what you do to one side of the equation, you do to the other. To solve, do the opposite of PEMDAS. Isolate the variable, z.
First, subtract 12 from both sides:
25 = 4.5z + 12
25 (-12) = 4.5z + 12 (-12)
25 - 12 = 4.5z
13 = 4.5z
Isolate the variable, z. Divide 4.5 from both sides:
(13)/4.5 = (4.5z)/4.5
z = 13/4.5
z = ~2.89 (rounded).
2.89 is your answer.
