Anthony's math teacher finds that there's roughly a linear relationship between the amount of time students spend on their homework and their weekly quiz scores. This
relationship can be represented by the equation y = 57 + 6.3.x, where y represents
the expected quiz score and a represents hours spent on homework that week. What
is the meaning of the x-value when y=99?

sum= when you add is how much the whole amount is

distance= when you use angles and it means how far it goes

step-by-step explanation:

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

the answer would be c:   ax + b = ax + c
