Melissa’s family is driving out of state to her grandmother’s house. They know that it takes 20 gallons of gas to get there, and the cost of three gallons of gasoline is $10.50. How much should the family budget to make the one-way trip?

Step-by-step explanation:

We khow that 3 gallons of gasolone are worth 10.50 dollars and it takes 20 gallons to do the one way trip .

we can say that :

3 gallons ⇒ 10.5 dollars

        20 gallons⇒ x

x= (20*10.5)/3

          =70

we deduce that : the familly badget must be equal to 70 dollars

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
