9. C. $2.00

10. B. $18.00

11. C. $1.53

12. A. $19.53

Step-by-step explanation:

10%, or 1/10th of 20 dollars is 2 dollars.

The movie, therefore, will cost 2 dollars less, or 18 dollars before tax.

To find tax, multiply the total (after price reduction) by the percentage tax (as a decimal, 0.085%), which gives you 1.53.

Add the tax and the initial cost together to get the total cost.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
