21/2 divided by 3 1/3 = s divided by 4 1/4 . what is s?

  3 3/16

Step-by-step explanation:

You want s such that ...

  (2 1/2)/(3 1/3) = s/(4 1/4)

Multiplying by 4 1/4 gives ...

  s = (4 1/4)(2 1/2)/(3 1/3)

A calculator can help you find the value of this expression. As a decimal, it is ...

  3.1875

If you're familiar with decimal equivalents of fractions, you know this can be written as the mixed number ...

  3 3/16

_____

If you do the above math the "pencil and paper" way, you get ...

  s = (17/4)(5/2)/(10/3) = (17·5·3)/(4·2·10) = 51/16 = 3 3/16

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
