Answer:

The answer is D. -5.

Step-by-step explanation:

Substitute the variables: 2(2) + 4(-1) - 5(1)

Multiply 2 by 2, and you get 4. Add 4 by the product of 4 and -1, which is -4, and you get 0. Subtract 0 by the product of 5 and 1, which is 5, and you get -5.


I hope this helped! :-)

Tom [10]

Answer:

0.08 minutes for a kilometer.

Step-by-step explanation:

If the track is 25 kilometers, and he runs 25 kilometers in 2 minutes, he runs a kilometer in 2÷25 minutes or 0.08 minutes which is 4.8 seconds.

I'm pretty sure the track isn't 25 kilometer or he can't run a lap in 2 minutes. But if so, the answer is 0.08 minutes.
