Alejandra drove from michigan to colorado to visit her friend. the speed limit on the highway is 70 miles/hour. if alejandra combined driving time the trip was 14 hours, how many miles alejandra drive?

980 miles.

Step-by-step explanation:

Method - 1

Alejandra drove her car in one hour           70 miles.

Alejandra drove her car in 14 hours             (70*14) = 980 miles.

Method - 2

To find the distance of Michigan to Colorado, we have to multiply the speed by the time.

Therefore, distance = (Time*Speed)

We can find it by this alternative way, distance = 14 hours*70 miles

                                                                              = 980  miles per hour

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1
