Dean ran 1 2/5 miles. sheila ran three times as far as dean. how far did sheila run?

-4 1/5

Step-by-step explanation:

-1 2/5 times 3 equals:

First make the fraction a mixed number.

-that is 7/5

Then you must times 7/5 to 3

-that equals 21/5

then you must simplify

the answer is

-4 1/5

graph #4 (last graph) depict the function   f(x)= -m(x-d)^1/5 i

step-by-step explanation:

we know that

m=slope

but in this function slope is -m that means slope is decreasing and it is decreasing by 1/5 points down the x-axis.

which is shown in graph four

a decreasing slope down x-axis by 1/5 points.

hence 4th graph is the right option for this.
