Answer:

Step-by-step explanation:

1. (-4, -2) (4, 0)

(0 + 2)/(4 + 4)= 2/8= 1/4

2. (-1, 2) (1, -3) = (-3 - 2)/(1 + 1) = -5/2

3. (-2, 3) (0, 0) = (0 - 3)/(0 + 2) = -3/2

faltersainse [42]

Answer: The number of rolls of paper is $2\dfrac{1}{2}$ .

Step-by-step explanation: Given that Andy is hanging wallpaper in his kitchen. 6 rolls of wallpaper is used to cover $2\dfrac{2}{5}$ of the walls.

We are to find the number of rolls of paper used per wall.

We will be using unitary method to solve the given problem.

We have,

$2\dfrac{2}{5}=\dfrac{12}{5}.$

Now, number of rolls used to cover $\dfrac{12}{5}$ of the walls = 6.

Therefore, number of rolls used to cover 1 wall is given by

$\dfrac{6}{\frac{12}{5}}=\dfrac{5\times 6}{12}=\dfrac{5}{2}=2\dfrac{1}{2}.$

Thus, $2\dfrac{1}{2}$ rolls of paper used per wall.
