Question

Evaluate expression when x = 10, y = -2, and z = -5 xz divided by - y

Answer 1

Based on what you wrote, if you substitute x and z so it will be 10 multiplied by -5, you would get -50. Then, if you divide -50 by 2, since -y would be substituted for -2 but since there’s a minus sign it would make it positive, you would get -25. So, the answer is -25.

Answer 2

25

Explanation:

10(-5)/-2

times x by z and divide by y

10 times -5 makes it -50 because a positive times a negative makes it a negative

then divide -50/-2

and because 2 negatives cancel each other out it's basically just 50/2 which equals 25.
