12n +9 = 6 - 311
How many solutions does the equation have?

One Solution

Step-by-step explanation:

We can figure out the steps for this equation by separating the variables in the left side and the whole numbers on the right side, what you can essentially do is separate them and the equation will look like

12n = -9 + 6 -311

then,

12n = -314

which gives you, approximately

x = -26.16667.

Hope this helped!

a negative exponent is translated as follows:

so, we have

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
