Which inequality best models the situation if variable d is the distance in kilometers?

Matt wants to run more than 12.25 kilometers each weekend. Show the possible distances he may run.









A.

d < 12.25 and d may be a negative number.








B.

d <12.25 and d must be a positive number.








C.

d > 12.25 and d may be a negative number.








D.

d > 12.25 and d must be a positive number.

Answer 1

D, because he wants to run MORE than 12.25 kilometers. > is the greater sign. If you used a negative number as d, he wouldn't run at all. If you used <, the less than sign, he would be running less than what he wants to run.
