1) It should be the opposite of what you put; 9 - n

2) Correct; y/22

3) Correct; 57 + b

4) Correct; 2/3x

5) Correct; c - 18

6) Correct; 2m + 25

7) Should be opposite of what you put; 8/2z

8) Correct; 2 + r²

9) I would just make the expression 40 - d since that's what it looks like your homework wants you to do; 40 - d

10) Correct; 1 + b

11) Correct; c/4

12) Not sure what you did there, but all you have to do to convert hours into minutes is to multiply the hours by 60; 60h

13) 75/5 = 15; Unit rate: \frac{\$15}{1~video~game}

14) 600/8 = 75; Unit rate: \frac{75~students}{1~class}

15) 32/4 = 8; Unit rate: \frac{8~pencils}{1~box}

2) you should put it in fraction terms, your answer is right, but it looks better as y/22

4) you don't need the dot, you can just write 2/3 x

7) same thing as 2, 2z/8

11) same thing as 2, c/4

They're all right :)
