The length of a rectangular room is 3 feet less than twice the width. If the perimeter of the room is 48 feet what is it’s length

15 feet

Step-by-step explanation:

length= 2w-3

width=w

2(2w-3+w)=48

2(3w-3)=48

6w-6=48

w-1=8

w= 9

length= 2(9)-3

length= 15

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
