What is this? -|2x+3|=1

This is an absolute value equation, and it has no solutions.

Step-by-step explanation:

If you don't know what they are, it is an equation with an absolute value in it. For this specific problem, there is no solutions, because to start, you have a negative sign before the absolute value. This means we have to divide by negative one to get rid of it. But we also have to do the same on the other side, to balance the equation. So we end up with |2x+3|=-1. But there is a problem. The meaning of absolute value is the distance from some number to 0, which means it will always be positive. But if we look back at the simplified equation, it says that the absolute value of 2x+3 is negative. And no matter what 2x+3 is, it will ALWAYS be positive. So that is why it has no solutions.

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
