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

i got 86 for this

hope this !

if you need an explanation just ask

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
