9) 42/5= 8.4 but you can't have part of a car so round up to get 9 cars 
10) 39.75/3= $13.25 per pair
11) 500/22=22.72 repeating, I would say an average of 23 mile per gallon
12) Kilograms- 0.01 and milligrams- 10,000
13) 112/35= 3.2 or 4
14)162 times 210= 34020 and 51 times 81= 4131
34,020-4,121= 29,889 ft and 3,321 yds

I really hope that I helped you!!!

The width of a rectangle measures (3v-3w) centimeters, and its length measures (5v-9w) centimeters. Which expression represents
Alex17521 [72]

Answer: The Perimeter of the rectangle, P= 16v −24w

Step-by-step explanation:

Perimeter of a rectangle  = 2( L +W) =   2L + 2W

The width of a rectangle is given as  (3v-3w) centimeters,

its length is given as (5v-9w) centimetres

The Perimeter,P will now be  = 2L + 2W

P=2( 3v-3w) + 2( 5v-9w)

P=6v  −6w + 10v  - 18 w

 adding like terms

P=6v + 10v  −6w −18 w

P= 16v −24w
