Greeley [361]

Answer:

The answer to your question is below

Step-by-step explanation:

Data

Volume = 24 in³

Process

1.- Find the prime factors of 24

24 2

12 2

6 2

3 3

2.- Volume of a rectangular package

Volume = length x height x width

3.- Possible values are, combine the prime factors to find the volume

Volume = 4 x 2 x 3 or

Volume = 2 x 4 x 3

Volume = 3 x 2 x 4

Volume = 2 x 2 x 6

Volume = 6 x 2 x 2

Volume = 2 x 6 x 2

Volume = 12 x 2 x 1

Volume = 1 x 12 x 2

Volume = 2 x 1 x 12

Write an equation for the line parallel to y= -2x+1 that contains (-2,5)

grin007 [14]

Answer:

y = - 2x + 1

Step-by-step explanation:

Parallels line have the same slope, when an equation is in the form y= mx + b, m is the slope. In this problem slope = - 2

Now with the slope what is missing is the y-intercept, the problem says that the line contains the point (-2, 5), replacing that point in the equation you can solve it to find the y-intercept

y = mx + b

5 = (-2)(-2) + b

5 = 4 + b

1 + b

y = - 2x +1

Enter the value for x that makes the equation 1/2 (4x+12)+5x=30 true.

8090 [49]

First, distribute the (1/2) into (4x+12) by multiplying them.

The equation becomes:

2x + 6 + 5x = 30

On the left side, combine “like terms” through addition.

7x + 6 = 30

Subtract 6 from both sides:

7x = 24

Finally, get x alone by dividing both sides by 7:

x = 24/7, or if you wanted to round the decimal answer, it’s about 3.429.
