Answer:
Step-by-step explanation:
20% discount is 1/5 x 68 = 13.60
So pre-tax price is 68 - 13.60 = 54.40
Add sales tax:
54.40 x 1.06 = 57.66
so the answer is C
1. x=2
2. x=-3
3.x=3
4. x=7
5. x=111/11
It's asking you to find what the value of x and y. You need to subtract the 6x to the other side of the first equation so you can plug the y value into the second equation.. so the second equation should look like 2x+3(-6x+9)=-5. Then you would distribute the 3 to simply it father. So the equation will be, after that, 2x+-18x+27=-5. Then you combine like terms, so it will be -16x+27=-5. Now you would subtract the 27 to the other side and you will get -16x=-22. Now you divide by -16, to get x=-38. Now you have your x value and you can plug it in to find the y value. I would use the first equation just because it will be less work. So you will set it up like 6(-38)+y=9 . Now you just finish the equation. So it should look like this...
-228+y=9
Y=230
Multiply 1/3 by 9 and get 9/3 which is 3 pizzas. 3 pizzas is your answer
$106 dollars since 6% of 100 is 6 and u add 6 dollars to 100 and u get $106
