How do you figure out sales tax?
monitta

Answer:

Step-by-step explanation:

You divide the price with 9.25.

For example, if I wanted to buy a pouch(3.00) and pens(4.59), and the total without tax was 7.59 (add the prices), the tax would be 0.70 because 7.59/9.25=0.70. If I add 0.70 to 7.59, I would have to pay 8.29.

Hope this helps!

Use the model to solve for x. <br> A) no solution <br> B) x = 1 <br> C) x = -1 <br> D) x = 10/4
andreev551 [17]

Answer:

x = -1

Step-by-step explanation:

The equation is -2x + 3 = 2x +7

Group the terms together. Don't forget to change the sign

-2x -2x = 7-3

-4x = 4

Divide both sides by 4

-x = 1

Flip it over

x = -1
