Zoe paid $18.60 in sales tax and tips for her dinner. The sales tax rate is 11%and she tipped 20% (The sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax.)
What was the price of Zoe's dinner, before sales tax and tip?
Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
Sales tax + tips for dinner = 18.60
The sales tax rate is 11%, and she tipped 20%. Given that the sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax. Let x be the original price
Sales tax = 11% * original price = 0.11 * x= 0.11x
Tips for dinner = 20% * original price = 0.20 * x = 0.2x
We know Sales tax + tips for dinner = 18.60
0.11x + 0.2x = 18.60
0.31x = 18.60
Divide by 0.31 on both sides
x = 60

Answer:
The slope is 1
Step-by-step explanation:
Point slope equation is y-y1/x-x1
-2-(-1)/-3-(-2)
-2+1/-3+2
-1/-1=+1
When graphing y = 3x + 5,
what is the first step?
Answer:
The first step would be to plot the y-intercept. In this equation, the y-intercept is 5. The ordered pair is (0, 5), because (x, y).
You go up 5 from the origin (the center of the graph, (0, 0) ), and plant a dot on the y-axis.
If you need help from there, then ask in the comments.

Answer:
8.5
Step-by-step explanation:
since it is the same as ABC, 2x-1=16
add the 1 to both sides which gives you 2x=17
then divide each side by 2 which gives you x=8.5

what is the answer to x + 5 = -6
Answer:
x=-11
Step-by-step explanation:
If you subtract the 5 on both sides, you get -11.
I should explain further. So if you subtract the 5 on the left side, it will cancel out. Subtracting the 5 on the right side will give you the equation, -6 - 5, which is equal to -11.

Use trig identities to verify this expression:
((1-tan^2(x))/(sec^2(x))=cos(2x).
Answer:
See below
Step-by-step explanation:
Verify the expression:
((1-tan^2(x))/(sec^2(x))=cos(2x)
-----------------------
(1-tan^2(x))/(sec^2(x) =(1-tan^2(x))/(1/cos^2(x) =(1-tan^2(x))*cos^2(x) =cos^2(x) - sin^2(x) = cos^2(x) - (1 - cos^2(x)) =2cos^2(x) - 1 =cos(2x)Done
Teresa is going with her family to watch
professional barrel racers. Her family
buys 6 tickets. They have a coupon for
$1.50 off each ticket. They pay $52.50
altogether for their tickets. Write an
equation that you could use to represent
the situation. What is the price of a ticket
before using the coupon?
Answer:
6 * (x - 1.50) = 52.50 ; 10.25
Step-by-step explanation:
Given that :
Number of tickets purchased = 6
Coupon off per ticket = 1.50
Total Amount paid for tickets = $52.50
Let x = initial price of ticket :
Number of tickets purchased * (Initial ticket price - coupon) = total amount paid
6 * (x - 1.50) = 52.50
6x - 9 = 52.50
6x = 52.50 + 9
6x = 61.50
x = 61.50 / 6
x = 10.25
Hence, initial price of ticket = $10.25
AB=3x
BC=10
AC=4x+1
X=
AB=
AC=
solution:
AB +BC = AC
3x +10 = 4x-1
10-1 = 4x-3x
9 = x
X=9
AB =3×9=27
AC = 4×9+1 =37

PLEASEEEEEEESE! thanks! During a company's first full year in business, the price of oil increased $50. In the second year of business, the price of oil went down $50\%$ from its price at the beginning of that year. Its price at the end of the second year is what percent of its price at the beginning of the first year?
Answer:
the actual answer is 75 percent of its price
Step-by-step explanation:
Answer:
75
Step-by-step explanation:
Let the initial cost of oil be x. After the first year, the price of oil is 1.5x. After the second year, the price of oil is 0.5 ∙ 1.5x = 0.75x.
This is 75 percent of its price at the beginning of the first year.

HELP MATH LAST ONEE!! :D MARKING BRAINLISEST!
Answer:
y = -11
Step-by-step explanation:
The slope-intercept form of an equation of a line:
y = mx + b
m - slope
b - y-intercept → (0, b)
We have the slope m = 0 and the point (0, -11) → b = -11.
Substitute:
y = 0x - 11 = -11
It's a horizontal line.
Answer:
Step-by-step explanation:
Slope-intercept form: [tex]y=mx+b[/tex] when [tex]b[/tex] is the y-intercept and [tex]m[/tex] is the slope
The slope is already given in the question: 0
The y-intercept is the value of y when x is equal to 0. We can see that the given point, (0,-11) also tells us this. When x is equal to 0, y is equal to -11. Therefore, the y-intercept of the line is -11.
Finally, we plug the slope and the y-intercept back into the original equation.
[tex]y=mx+b\\y=0x+(-11)\\y=0-11\\y=-11[/tex]
