Help me please/yuigigkhohlj

We have: PZ = 1/2 XZ ( Z is the middle point of XZ )

=> 22 = 1/2(5x - 11)

=> 1/2(5x - 11) = 22

=> 5x - 11 = 22 : 1/2

=> 5x - 11 = 44

=> 5x = 44 + 11

=> 5x = 55

=> x = 55/5 = 11

ANSWER: x = 11

Ok done. Thank to me :>

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
