* 1. Which terms can be combined in the following expression? *
4x² - 5y + 6x + 4y - 7
0 4x² and 6x
O-Sy and 4y
O 4y and - 7
-5y and 6x

-5y and 4y

Step-by-step explanation:

this is because both of them have the same degree of variables, regardless of the signs of their coefficients, you can combine terms that follow the stated points above.

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
