Ashlynn, Troy, and Edwin had a challenge to see who could run the farthest in a month. Ashlynn ran 19 miles. Troy ran 3 times as many miles as Edwin, and Edwin ran 4 times as many miles as Ashlynn. How
many miles did Troy run?

Troy ran 228 miles.

Step-by-step explanation:

Ashlynn (a) ran 19 miles. Troy (t) ran 3 times as many miles as Edwin, and Edwin (e) ran 4 times as many miles as Ashlynn.

So,

a=19

E=a•4

t=e•3

Knowing a=19, we can solve the first equation. e=19•4, 19•4=76 so e=76

Knowing e=76 we can solve the second equation t=76•3, 76•3=228 so t=228

Ashlynn is my name!

Step-by-step explanation:

ok

step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
