A

Step-by-step explanation:

if you get the y amount and multiply it then add 9 you would get sandy's amount

equation would be:(3y+9)

B

Step-by-step explanation:

Because Sandy have 9 more than henry, so +9. Henry have 3 time as Roger. Roger's CD is y. 3 times mean multiply by 3. So, 3y, but we have to subtract a y because it is asking how many Sandy have MORE than Roger, so 2y. Then add the 9 and it will be (2y+9) CD's that Sandy have more than Roger.

step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
