Answer:

The correct answer is A. Divide both sides by positive 5

Step-by-step explanation:

Let's solve the equation for finding z and the necessary steps to do it:

5z - 3 = 12

5z = 12 + 3 (Adding 3 at the right side and subtracting 3 at the left side)

5z = 15 (Adding 12 plus 3 at the right side)

5z/5 = 15/5 (Dividing by positive 5 at both sides)

z = 3

The correct answer is A. Divide both sides by positive 5

alexdok [17]

Answer: Eliza wakes up at 6:25 A.M.

Step-by-step explanation:

What I did is first used the 45 minutes to make the time 10:00 P.M. which leaves you with 8 hours and 25 minutes, then i added the 8 hours onto 10:00 P.M. which leaves you at 6:00 A.M. with 25 minutes left, then you add the 25 minutes onto 6:00 A.M. which puts it at 6:25 A.M.
