George is putting trim around his rectangular deck, including the gate. He will need 44 feet of trim to do the entire deck. If the deck is 12 feet long, how wide is the deck? 20 feet
8 feet
22 feet
10 feet

10 feet

Step-by-step explanation:

perimeter of the deck=44 feet

P=2 length+ 2 width

44=2(12)+2w

44=24+2w

2w=44-24

w=20/2 ⇒ w=10 feet

check: P=2l+2w ⇒ 2(12)+2(10) ⇒ 24+20=44 feet

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

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
