Solve:

2x - 3 = - 15

Add 3 to both sides:

2x - 3 + 3 = -15 + 3

2x = -12

Divide both sides by 2:

x = -6

In a study, the weights and the lengths from nose to tail of 8 female cheetahs were recorded and graphed on a scatter plot. Which is the most reasonable prediction for the weight of a female cheetah that is 6 feet long?

Without the actual scatter plot and regression line or equation, it's difficult to make an accurate prediction. However, assuming there is a positive correlation between length and weight (i.e. as length increases, weight increases), a reasonable prediction would be that the 6-foot long female cheetah would weigh more than the average weight of the 8 recorded female cheetahs.

To make a rough estimate, you could look at the general trend of the scatter plot and find the approximate weight that corresponds with a length of 6 feet. For example, if the scatter plot shows that most cheetahs with a length of 5 feet weigh around 100 pounds, and most cheetahs with a length of 7 feet weigh around 150 pounds, you could estimate that a 6-foot cheetah would weigh around 125 pounds.

However, without more information, any prediction made would be a rough estimate and not necessarily accurate.

Ms. Malloy is painting one side of a rectangular barn door. The door is 80 inches high and 40 inches wide. What is the area of one side of the door?

The area of one side of the door can be found by multiplying the height and the width of the door:

Area = height x width

Area = 80 inches x 40 inches

Area = 3200 square inches

Therefore, the area of one side of the door is 3200 square inches.

Solve:

- 80 = 5m

To solve for m, we need to isolate it on one side.

We can start by adding 80 to both sides:

-80 + 80 = 5m + 80

0 = 5m + 80

Next, we can subtract 80 from both sides:

-80 - 80 = 5m

-160 = 5m

Finally, we can divide both sides by 5 to solve for m:

m = -32

Therefore, the solution is m = -32.
