When r = 8 and s = 5, what is the value of r +2s
- 9?

9

Step-by-step explanation:

If we substitute the variables for the numbers, the equation looks like this:

8+2(5)-9

Because 2s was multiplying 2 by s in the original equation, we can do that step first!

8+2(5)-9

8+10-9

Personally, I think it's a lot easier to subtract 9 from 10 first, but you can solve this part in any order.

8+10-9

8+1

This is the last part; we just have to add 8 and 1 now!

8+1=9

Hope this helps!!! Have a wonderful day C:

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.
