An empty 5-gal water jug weighs 0.75 lb. with 3 c of water inside, the jug weighs 2.25 lb. which equation models the jug’s weight y when it contains x cups of water?

y=.75 x=.75 for one cup of water

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:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
