(the number line goes from -8 to 8)

- There is a P at - 5

- There is a Q at -3

- There is a R at -2

- There is a S at 2

C. point Q and point S

D. point R and point S

11 answers

The correct answer is option D. Point R and point S have a distance of 5 units between them.
Points P and Q are plotted on the number line.

(Number line goes from -8 to 8)

- P is at - 8

- Q is at 6

Which expression represents the distance between points P and Q?

A. | - 8 - (-6) |

B. | - 8 - 6 |

C. |8 - 6|

D. |6 - 8|
The correct answer is option B. | - 8 - 6 | represents the distance between points P and Q.
What is the value of 1/5 (6 + 8.5)?

A. 2.9

B. 7.7

C. 9.7

D. 14.9
The value of 1/5 (6 + 8.5) can be calculated as follows:

1/5 (6 + 8.5) = 1/5 * (14.5) = 14.5/5 = 2.9

Therefore, the correct answer is option A. 2.9
Last year, Ted's salary was $42,000. He donated 1/25 of last year's salary to charity. How much did Ted earn last year after his donation?

A. $31,500

B. $40,320

C. $43,680

D. $52,500
To find out how much Ted earned last year after his donation, we need to subtract the amount he donated from his salary.

The amount Ted donated is 1/25 of $42,000. We can find this by multiplying 1/25 by $42,000:

($42,000) * (1/25) = $1,680

To calculate Ted's salary after his donation, we subtract the donation amount from his original salary:

$42,000 - $1,680 = $40,320

Therefore, the correct answer is option B. $40,320.
A grocery store charges $0.75 per donut. Which equation can be used to find c, the total cost, in dollars, to buy D donuts?

A. c = 0.75 + d

B. c = 0.75d

C. D = 0.75 + c

D. D = 0.75c
The equation that can be used to find the total cost, c, in dollars, to buy D donuts is:

B. c = 0.75d

In this equation, d represents the number of donuts being bought, and 0.75 represents the cost per donut. Multiplying the cost per donut, 0.75, by the number of donuts, d, gives us the total cost, c.
Harrison reads 15 minutes per day for a project. The total number of minutes Harrison reads for the project is proportional to the number of days since he started the project.
The equation shown represents the total number of minutes Harrison has read since he started the project.

Y = 15x

What does x represent in the equation?

A. The total number of minutes Harrison reads for a certain number of days for the project.

B. The total number of pages Harrison has read since he started the project.

C. The number of minutes Harrison reads per day for the project.

D. The number of days Harrison has read since he started the project.
In the equation Y = 15x, x represents the number of days Harrison has read since he started the project.

Therefore, the correct answer is option D. The number of days Harrison has read since he started the project.
