Answer:

-4x-6x=-20=

x=2

-3(2x-3)=33=

x=-4

4x+3x+2x=180

x=20

Step-by-step explanation:

-4x-6x=-20                                

-4+(-6)=-10x

-10x=20 (divide both by 10)

x=-2 (divide by -1 to get positive)

x=2

-3(2x-3)=33

-6x+9=33

     -9 .  -9

-6x=24 (divide both by -6)

x=-4 (divide by -1 to make positive)

4x+3x+2x=180

(combine like terms)

9x=180 (divide both sides by 9)

x=20

A rectangle whose perimeter is one hundred four feet. Has a width that is te feet shorter Then its length. What are the dimensio
Stolb23 [73]

Length of the rectangle is 24.5 ft and width is 27.5 ft

Step-by-step explanation:

  • Step 1: Let the length of the rectangle be x, then width = x - 3. Find dimensions when perimeter = 104 ft

Perimeter = 2(length + width)

⇒ 104 = 2(x + x-3)

⇒ 104 = 2(2x - 3)

⇒ 104 = 4x - 6

⇒ 4x = 110

∴ x = 110/4 = 27.5

⇒ x - 3 = 24.5
