Use algebraic rules of equations to predict the solution type to the system of equations. Include all of your work for full credit.

Step-by-step explanation:

There are infinite  number of solutions to the system

Let us start by re-writing the second equation;

We have it as;

6y + 3x = 30

Divide through by 3

x + 2y = 10

That means we have same equation in 2 places

This means there are infinite number of solutions that can satisfy the system as the two equations are same

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
