Answer:
13) x=n-11
15) x=3*10
Step-by-step explanation:
I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!
I think it’s the one with acute because it’s less than 90 degrees
X = 10 because if you multiply everything by 2 you get x + 2 = 12. X = 12- 2 which is 10
