55.99 dollars gift with 18% coupon and 7.25% sales tax. What is the final cost?
Answer:
I think it is $91.89.
Step-by-step explanation:
1. Take the number and add sales tax by multiplying 0.0725 ( since that is what the percentage is in a decimal form). Then add that to the original and you have what it would be plus sales tax: $60.05.
2. Then you would need to multiply by 0.18. You would get 10.809
3. Next, subtract the 10.809 from $60.05 and the answer is $49.24.

1)Solve 3x+2= 5
A. Model 3 2 x+ = 5.
B. Perform the step to have the variables (circles) alone on one side.
C. Write the resulting step.
D. Divide the variables (circles) and numbers (squares) into equal groups.
E. Show the value of one group.
The value of x in the equation, 3x + 2 = 5 is 1.
In order to solve this equation: 3x + 2 = 5, take the following steps:
Combine similar terms together:
3x = 5 - 2
Add the similar terms together
3x = 3
Divide both sides of the equation by 3 in order to make x the subject f the formula
3x / 3 = 3 /3
x = 1

Answer:
0
Step-by-step explanation:
the x-value doesn't change
Hello! :)
We can use the slope formula:
[tex]\frac{y2-y1}{x2-x1} \\\frac{1-7}{-5-(-5)} \\\frac{-6}{-5+5} \\\frac{-6}{0} \\[/tex]
The slope is undefined. Here's something you should remember:
If the x-coordinates are the same, then the slope is undefined.Hope it helps! :)

We know that the sum of supplementary angles is 180°
=> 55 + ang. B = 180°
=> ang. B = 180-55 = 125°

[tex]Sin QPS=\frac{Opposite}{hypotenuse}[/tex]
sin 15° = [tex]\frac{QS}{PQ}[/tex]
QS= sin 15° * PQ
QS = 0.2588 * 12.6 = 3.36088 ≈ 3.4m
a. The length of QS = 3.4m
b. [tex]cos QPS=\frac{Adjacent}{Hypotenuse}[/tex]
Cos 15° = [tex]\frac{PS}{PQ}[/tex]
PS = Cos 15° * PQ

Answer:
Step-by-step explanation:
0056 because 1% is 72 so you know it’s going to have to be less then 72. So to get your percent you divide 40 by 7200 so 40/7200. This will get you .00555556 which I rounded to .0056

andre is solving the inequality 14x+3 is less than or equal to 8x+3.he first solves a related equation
14x+3=8x+3 this seems strange to Andre. He thinks he probably
14x=8x made a mistake.What was his mistake?
8=14
Answer:
14x+3=8x+3
14x+3 -3 = 8x+3 -3
Cancels out the 3
14x = 8x
14x - 8x = 8x -8x
Cancels out the 8x
14x = 0
x = 0
Step-by-step explanation:
Andre should have collected the like terms in order to have all the variables x on one side before taking the difference.
Inequality expressionGiven the inequality expression solved by andre expressed as:
14x + 3 ≤ 8x + 3
Simplify to have:
14x - 8x ≤ 3-3
6x ≤ 0
x ≤ 0
Hence andre should have collected the like terms in order to have all the variables x on one side before taking the difference.

Step-by-step explanation:
The new donut shop sold 210 donuts in the first hour. At this same rate, how many donuts would the shop sell in 90 minutes? Solve the word problem using the unit rate.
Hey this is me again ....
[tex] \frac{210}{60} = \frac{x}{90} \\ [/tex]
[tex] \frac{21}{6} = \frac{x}{90} \\ [/tex]
Multiply both sides by 90
[tex]90 \times \frac{21}{6} = 90 \times \frac{x}{90} \\ [/tex]
[tex]15 \times 21 = x[/tex]
[tex]x = 315[/tex]
So that shop would sell 315 donuts in 90 minutes
Holy crab that is too much donuts impressive....
