Answer:
All of them
Step-by-step explanation:
All we have to do is replace the x and y with their following coordinates
A.(5, -5/6) - - > 5(5) + 12(-5/6) = 25 + (-10) = 15
15 = 15
Yes
B. ( -3, 5/2) - - > 5(-3) + 12(5/2) = -15 + 30 = 15
15 = 15
Yes
C. (-6, 15/4) - - > 5(-6) + 12(15/4) = -30 + 45 = 15
15 = 15
Yes
D. (-5, 10/3) - - > 5(-5) + 12(10/3) = -25 + 40 = 15
15 = 15
Yes
Answer:
$60
Step-by-step explanation:
To find how much Zoe paid before the sales tax and tip, we first need to consider the amount she paid in sales tax and tips.
Sales tax + Tips = $18.60
Let x = original price
Sales tax = 11% * original price
Sales tax = 0.11 * x
x= 0.11x
Tips = 20% * original price
Tips = 0.20 * x
x = 0.2x
Now that we have a value for both the sales tax and tips, we can then proceed to find the original price by:
0.11x + 0.2x = 18.60
0.31x = 18.60
Now we need to divide both sides by 0.31 to find x.
x = 60
Zoe's dinner before the sales tax and tips was $60.
