Answer:

       (-1, -2)

x = -1          y = -2

Step-by-step explanation:

y= -2x-4

y= 3x+1​

Substitution:

3x + 1​ = -2x - 4

5x + 1 = -4

5x = -5

x = -5 ÷ 5

x = -1

y= 3x+1

y= 3(-1)+1​​

y = -3 + 1

y = -2

Answer:

It will take 6/13 hours to walk one mile

Step-by-step explanation:

= 3/2 * 4/13 = 6/13 hours

Nutka1998 [239]

We have given that,

A box of cereal has a volume of 144 inches squared.

The height of the cereal box is 12 inches, and the depth is 2 inches.

The volume of cone = 144 inches squared.

height=12 inches

depth=2inches

<h3>What is the formula of the cube?</h3>

Area of a cube = V = L * W * H

L-length

W-width

H-height

We have to determine the width cereal box.

Plug the given values in the formula

V = L * W * H

144=2×12×width

Width=144/24

Width=6inches

Therefore the value of the width is 6 inches.
