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

25

Step-by-step 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.

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.
