The latest thrill ride at a popular theme park takes roller coaster fans on an exciting ride. in
the first 20 seconds, it carries its passengers up a 100-meter hill, plunges them 72 meters
down, and quickly takes them back up a 48-meter rise. how much higher or lower from the
start of the ride are they after these 20 seconds? !

the answer is 15% decrease

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.

i think it might be a but you might want a second opinion

just sum

10 + 10 = 20
