Find WX and show work

Given:

In a parallelogram WXYZ, WX=4x+5 and YZ= 7x-22.

To find:

The WX.

Solution:

In parallelogram WXYZ,

            [Opposite sides of a parallelogram are equal]

Putting the given values, we get

Isolating variable terms.

Divide both sides by -3.

Now,

Putting x=9, we get

Therefore, the value of WX is 41.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
