Please help i also need an explination

4 rolls

Step-by-step explanation:

First we need to find the area of the wall

A = l*w

   = 8*16 = 128

Then we find the area that a roll of wallpaper will cover

A=2*20=40

Divide

128/40 =3.2

We must round up since we cannot buy part of a roll

We need 4 rolls

4

Step-by-step explanation:

Area of the wall = 8 × 16

= 128 ft²

One roll covers an area of:

2 × 20

= 40 ft²

She needs:

128/40 = 3.2 rolls

Since complete rolls are to be bought, she needs to buy 4 rolls

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
