Paul runs 4.8 km every morning. how many feet are in 4.8 km, given that 1 mile = 1.609 km and 1 mile = 5,280 feet?

Step-by-step explanation:

This is a conversion of units problem, so first you have 4.8 km and you need to convert it to feet.

First you take the quantity you need to convert:

4.8km

Then you put a factor, in the denominator you put the conversion factor with the same units that the number that you want to convert, that is:

Then in the numerator you put the second unit that you have, in this case, the problem gives you that 1 mile = 1.609km, so:

Then, as the problem says that convert the 4.8km to feet, you put the next factor in the same way:

Finally, you multiply the initial quantity and the numerators and divide by the denominators, and you have:

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

answer: this is not a question
