Jesse and larry entered a pie eating contest. jesse ate 5 less than twice as many pies as larry. they ate a total 16 pies. how many pies did larry eat?

Let the x = # of pies Larry ate

Jesse ate 2x-5 pies

Total = 16

Your equation is:

x + (2x-5)=16

3x-5=16

3x=21

x = 7

Larry ate 7 pies.

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
