Multiplying a listed price by the percent can get you the sales tax, and then you can add.
[tex]80*0.07=5.6[/tex]
(0.07 is 7% converted into a decimal)
[tex]80+5.6=85.60[/tex]
So the item is $85.60 after sales tax.
You may also notice that multiplying the listed price by 1.07 will get you the same answer, without the need to add the sales tax.
[tex]80*1.07=85.60[/tex]

find y if x = -3 whats the answer
A. y = 1/3 (-3) - 3 = - 6
B. y = 2(-3)^2 - 3(-3) - 2
= 2(9) - 3(-3) - 2
= 18 + 9 - 2
= 25
C. 2(-3) - 5y =4
- 6 - 4 = 5y
y = - 2
Answer:
A = -6
B = 25
C = 2
Step-by-step explanation:
-3*1/3 = -1, and -1-5=-6
2(-3)^2=2(9)=18 -3*-3=9 18+9=27 27-2=25
for the last rewrite the equation
2x-4=5y
-6-4=-10
-10=5y
y=-2

An up-and-coming artist has 85 followers on Twitter and this number doubles every week. In what week will the artist first reach 1,000 followers? Use at least two different methods to come up with your answer.
Answer:
5.8 , which approximately is 6 weeks.
Step-by-step explanation:
the first method is the short one since u just have to double the 85 then divide to 1000.
1000 ÷ ( 85 × 2)
1000 ÷ 170 = 5.882,,,,,. round off to whole number to get 6.
the second method is the addition method.
we start by 85 then keep doubling 85 for every week........inshort.......we add 170 to each weeks number to get the number of followers for the following week.
85 ⇒ 170 ⇒ 340 ⇒ 510 ⇒ 680 ⇒ 850 ⇒ 1020.
1st 2nd 3rd 4th 5th 6th week.
u notice that we add (85×2), 170, to get the following week's number of followers..
in 5 weeks..... the number of followers is yet to get to 1000.
when u divide, u get 5.8.....,and it is not logic to say 5.8823....weeks
since she reaches 1000 followers in the 6th week.......though there is an addition,,,, it is the most appropriate answer.
It will take [tex]6[/tex] week to reach [tex]1000[/tex] followers.
First, we are using two step to find the answers.
Division Addition
Division:
By given, A artist has [tex]85[/tex] followers.
Every week the no. of. followers is doubled .
Now, find how many week the artist reach [tex]1000[/tex] followers.
Since week followers is doubled,
So ,[tex]85*2[/tex]
Thus,
[tex]1000\div(85*2)\\\\=1000\div170\\\\=5.883[/tex]
Which is not possible .
Then, it take [tex]6[/tex] week to reach the [tex]1000[/tex] followers.
Addition:
By given, A artist has [tex]85[/tex] followers.
Every week the no. of. followers is doubled .
To find how many week the artist reach [tex]1000[/tex] followers.
Now, the first week has [tex]85[/tex] followers.
[tex]85[/tex] followers doubled.
[tex]85+85=170[/tex] followers doubled in every week .
Then,
Second week has [tex]85+85=170[/tex] followers.Third week has [tex]170+170=340[/tex] followers.Fourth week has [tex]340+170=680[/tex] followers.Fifth week has [tex]680+170= 850[/tex] followers.Sixth week has [tex]850+170= 1020[/tex] followers.Hence, the artist reach [tex]1000[/tex] followers in mid week of [tex]5[/tex] to [tex]6[/tex] week .
so, it approximately take [tex]5.88[/tex] week to reach [tex]1000[/tex] followers but which is impossible to take decimal in week .
Thus, the artist take [tex]6[/tex] week to reach the [tex]1000[/tex] followers.

A triangle has side length of
3.8q + 21.2 + 8.3r
The perimeter is all sides added together, therefore our equation looks like this:
[tex](1.7q + 9.3) + (2.1q + 6.7) + (8.3r + 5.2)[/tex]
However, we can get rid of the parentheses and add like terms together.
[tex]1.7q + 9.3+ 2.1q + 6.7+ 8.3r + 5.2[/tex]
[tex]1.7q + 2.1q + 9.3 + 6.7+ 5.2 + 8.3r [/tex]

Point B is on line segment AC. Given AB = 2x + 10, BC = x, and AC = 5x,
determine the numerical length of AC.
Answer:
AC = 25
Step-by-step explanation:
Since B is on the segment AC, then
AC = AB + BC, substitute values
5x = 2x +10 + x , that is
5x = 3x + 10 ( subtract 3x from both sides )
2x = 10 ( divide both sides by 2 )
x = 5
Thus
AC = 5x = 5(5) = 25

Use area of squares to visualize Pythagorean theorem
The diagram shows a right triangle and three squares. The area of the largest square is 55 units.
Answer:
A. 12 and 43
Step-by-step explanation:
Pythagorean theorem is given as = [tex] a^2 + b^2 = c^2 [/tex]
Where, a and b are the two legs of the right triangle, while c is the hypotenuse/longest leg of the triangle.
In the figure given, the side of the largest square = the hypotenuse of the triangle = c
While the side of the other squares = a and b respectively, of the triangle.
Area of square = s², where s is the side length of the square.
Since we are given that the area of the largest square = 55, this is also equivalent to c² in the Pythagorean theorem.
The side length of the largest square = √55 ≈ 7.4 = c
Therefore, to determine the area of the other squares, check the options given if they add up to give 55.
Option A: 12 + 43 = 55
Option B: 14 + 40 = 54
Option C : 16 + 37 = 53.
The correct possible areas of the smaller squares would be A. 12 and 43.

AB lies on a number line. The coordinate of point A is -6. Given that AB=20, what are two possible coordinates for point B?
Answer:
-26 or 14
Step-by-step explanation:
Given that
Coordinate of point A is -6.
Length of AB = 20
To find:
Coordinates for the point B = ?
Solution:
We are given that:
AB = 20
In other words, we can use modulus function to define the distance between A and B:
|Coordinates of B - Coordinates of A| = 20
Let the coordinates of B = [tex]x[/tex]
Kindly refer to the attached image for the given situation.
Point B might be either on the left or on the right side of A.
That means:
[tex]|x-(-6)| = 20\\\Rightarrow |x+6|=20[/tex]
Now, let us have a look at the modulus function:
[tex]|y|=\left \{ {-{y}\ if\ y<0 \atop {y}\ if\ y>0} \right.[/tex]
So,
[tex]|x+6|=\left \{ {-{(x+6)}\ if\ (x+6)<0 \atop {(x+6)}\ if\ (x+6)>0} \right.[/tex]
[tex](x+6 ) =20\\\Rightarrow x =14[/tex]
[tex]-(x+6 ) =20\\\Rightarrow x =-26[/tex]
Therefore, the answer is:
-26 or 14

You have money in your wallet, but you don't know the exact amount. When a friend asks you, you say that you have 100 dollars give or take 25. Write an inequality to describe the amount of money in your wallet.
Answer: 75 < x < 125.
Step-by-step explanation:
Let x be the amount of money in your wallet.
The phrase "100 dollars give or take 25" means wallet can have money between (100-25) dollars and (100+25) dollars.
i.e. 100-25 < x < 100+25
⇒ 75 < x < 125.
That means the amount of money in your wallet lies between 75 dollars and 125 dollars.
Hence, the inequality to describe the amount of money in your wallet is 75 < x < 125.

Answer:
Domain of f(x) = 2/7x - 2: (-∞, ∞)
Range of f(x) = 2/7x - 2: (-∞, ∞)
Domain of f(x) = |x + 3| - 1: (-∞, ∞)
Range of f(x) = |x + 3| - 1: [-1, ∞)
Domain of f(x) = -5x + 4: (-∞, ∞)
Range of f(x) = -5x + 4: (-∞, ∞)

We can use a graphing calculator to find the graphs.
Domain is the set of all x-values that can be inputted into function x.
Range is the set of all y-values that can be outputted from function x.

half of your baseball cards collection got wet and was ruined. you bought 19 cards to replace some that were lost. how many did you begin with if you now have 45.
Answer:
38 cards
Step-by-step explanation:
Assuming that you replaced all your baseball cards that were ruined, that would mean that you started with 38, because we know that 19 is half of all the baseball cards that were lost so 19*2=38
