What value can be added to 2/15 to make the sum greater than 1/2
answers: 1/15 , 8/30 , 5/15 , 8/15

2/15+1/15=3/15 which isn't less than a half

2/15+8/30=2/15+4/15=6/15 which isn't less than a half

2/15+5/15=7/15 which isn't less than a half

and 2/15+8/15=10/15 which is greater than a half, and when cancelled down is 2/3 which is definitely greater than a half:)

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.
