In Saras class, 2/5 of the students ride a bus, and 1/3 ride a car to school. The rest walk to school. Explain how you can find the fraction of students who walk to school. Find the fraction of students who ride a bus or car to school. Draw a diagram and use an equation to find your answer. Find the fraction of students who walk to scool. Draw a diagram and use an equation to find your answer.

Step-by-step explanation:

In Saras class, of the students ride a bus, and ride a car to school.

The rest

walk to school (simply subtract from one whole the fractions of students).

The fraction of students who ride a bus or car to school is

See attached diagram for pictorial representations (red diagram shows the fraction of students who ride a bus, blue - ride a car, green - walk to school)

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
