Can u guys answer these 2 questions for me w/ work shown and also label the ones u guys did so i won’t get them mixed up

The answer for number 9 is 11 and number 11 the answer is 6.

Step-by-step explanation:

9) x + 8 -y, use x = 20 and y=17

First, plug in your numbers for each variable.

20 + 8 - 17

Then, use PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction) to solve your equation which in this case goes straight across like this.

20 + 8 = 28 - 17 = 11.

11) 10 - x + y divided by 2; use x=5 and y=2

Once again, plug in your numbers.

10 - 5 + 2 divided by 2

In this problem, you do the division first which brings you to:

10 - 5 + 1

Then, you subtract and then add to get your answer of 6.

10 - 5 = 5 + 1 = 6.
