Imagine you went to the store and bought a video game for $12.98. This item is taxable at 6% tax and the total tax is $0.78. What is the total amount due?
Next, you decide to pay with a $20.00 bill. How much change will you receive after paying for your video game?
Using simple linear equations we calculate that the change left will be $6.24 .
The equals sign is used to indicate that two expressions on each side of the equal sign are equal in the many mathematical formulas that are utilized to form an equation.
Depending on the language, the definition of the word equation and its cognates may change slightly.The first step in solving a variable equation is to determine the precise values of the unknown variables that lead to the provided equality. The equation's solutions, often referred to as the variables for which the equation must be solved, are the values of the unknowable variables that satisfy the equality.Let the change received be x.
Therefore let us construct an equation for the situation
cost of game + tax + change = 20
or, 12.98 + 0.78 + x = 20
or, 13.76 + x = 20
or, x = 6.24
Therefore he will receive 6.24 after solving the equation.

find x
please and thank you
Answer: x = 65
Step-by-step explanation:
1) First find the mini triangles, left and right angles
We will be calling the left one A and the right one B.
2) Next use triangle sum to find B.
62 + 50 + b = 180
b = 68
3) Use triangle sum again to find A.
53 + 80 + a = 180
a = 47
4) Use triangle sum to find the top mini angle.
47 + 68 + c = 180
c = 65
5) Since x is in the vertical angle of c, they are equal
c = x

In accordance with analytic geometry, the equation that represents the line is y = - (1 / 4) · x - 6.
What is the equation for a line shown on a graph?
Herein we find the representation of a line set on a Cartesian plane. According to analytic geometry, line are represented by equations of the form y = m · x + b, where m, b are the slope and the y-intercept, respectively.
Both the values of the slope and the y-intercept can be found by knowing the location of two points lying on the line. If we know that (x₁, y₁) = (0, - 6) and (x₂, y₂) = (4, - 7), then we find the following system of linear equations:
b = - 6 (1)
4 · m + b = - 7 (2)
By (1) in (2):
4 · m - 6 = - 7
4 · m = - 1
m = - 1 / 4

The polynomial is x³ + 2x
If the zeros or roots of the polynomial are given, then the standard form of the polynomial can be found.
That is, a, b and c are roots of the polynomial, then the polynomial will be of degree 3 since 3 zeros are there and the factors of the polynomial will be , x-a, x-b and x- c.
Then the polynomial is, (x-a)(x-b)(x- c) = x³-(a+b+c)x-abc
Here the zeros of the polynomial are x = 0, x = i√2 and x = -i√2.
So the factors of the polynomial are (x-0), (x - i√2) and (x +i√2).

The coordinates of the orthocenter of triangle DEF are given as follows:
(6.67, -2).
How to find the orthocenter of a triangle?The orthocenter of a triangle is the point of intersection of the three altitude lines of the triangle.
Hence, we need to find two of the lines, and them find the intersection point between them, as the third line will necessarily intersect these lines at this point.
The midpoint of segment DE is:
(6, 1).
Which is the mean of the coordinates.
Vertex F is at point (8, -8), hence the slope of the line with these two points is:
m = (-8 - 1)/(8 - 2) = -9/2 = -4.5.
Hence:
y = -4.5x + b.
When x = 6, y = 1, hence we can find b as follows:
1 = -4.5(6) + b
b = 28.
Hence one line is:
y = -4.5x + 28.
The midpoint of segment EF is:
(8, -1.5).
Which is the mean of the coordinates.
Vertex D is at point (4, -3), hence the slope of the line with these two points is:
m = (-1.5 - (-3))/(8 - 4) = 0.375.
Hence:
y = 0.375x + b.
When x = 8, y = -1.5, hence we can find b as follows:
-1.5 = 0.375(8) + b
b = -4.5.
Hence the two lines that we have to find the intersection point is:
y = -4.5x + 28.y = 0.375x - 4.5.Then the x-coordinate of the orthocenter of the triangle is:
-4.5x + 28 = 0.375x - 4.5
4.875x = 32.5
x = 32.5/4.875
x = 6.67.
The y-coordinate of the orthocenter of the triangle is:
y = 0.375(6.67) - 4.5 = -2.

A store owner mixes 2 lbs of candy that cost x dollars pound with 3 lb of candy that costs $1.50 per pound. she sells the mix for $2.50 per pound. how much did the 3lb of the second type cost the owner?
Algebraic equations are mathematical equations that consist of unknown variables. These unknown variables can be represented with any letter of the alphabet.
The cost of 2 pounds(lb) of the first type of candy is $8
Note that: x represents the cost per pound (lb) of the first type of candy
The Algebraic equation for the above statement is given as:
2lb × $x + 3 Ib × $1.50 = $2.50(2lb + 3lb)
2x + 4.5 = 12.5
Collect like terms
2x = 12.5 - 4.5
2x = 8
Divide both sides by 2
2x/2 = 8/2
x = 4
The cost of the 1 pound of first type of candy is $4
The cost of 2 pounds(lb) of the first type of candy is calculated as:
2 x $4
= $8

Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50.
Let SSS represent the number of stacks of pancakes that Benjamin buys.
1) Which inequality describes this scenario?
Choose 1 answer:
Choose 1 answer:
(Choice A, Checked)
A
3.25+S \leq 303.25+S≤303, point, 25, plus, S, is less than or equal to, 30

B
3.25+S \geq 303.25+S≥303, point, 25, plus, S, is greater than or equal to, 30
(Choice C)
C
3.25+5.50S \leq 303.25+5.50S≤303, point, 25, plus, 5, point, 50, S, is less than or equal to, 30
(Choice D)
D
3.25+5.50S \geq 303.25+5.50S≥303, point, 25, plus, 5, point, 50, S, is greater than or equal to, 30
2) What is the largest number of pancakes that Benjamin can afford?
The correct option is D that is bill is equal to or greater than $30
3.25 + 5.5s < =30
The first step in building the inequality is modelling Benjamin's spendings.
He buys a chocolate milk that costs $3.25, plus S stacks of pancakes, each at $5.50. Thus, in total, his spendings are of:
3.25 + 5.25s
He wants the bill to be of at most $30, that is, his spending has to be at most $30, thus:
T < 30
3.25 + 5.5s < =30
Thus the correct inequality is option D which is 3.25 + 5.5s < =30

A circle's arc is referred to as a portion or section of its circumference. A chord of a circle is a straight line that might be created by joining the arc's two ends. A semicircular arc is one whose length perfectly divides the circumference of the circle.A circle's circumference forms an arc. An arc length is the length of the arc, whereas an arc measure is the measurement of the angle the arc makes at the center of a circle. This measurement can be expressed in radians or degrees. Using the fact that pi radians = 180 degrees, we can quickly convert between the two.Short arc BC is the difference between 360° and long arc BAC

Answer:
x = 60
Step-by-step explanation:
(2x + 15)° and 135° are corresponding angles and are congruent , then
2x + 15 = 135 ( subtract 15 from both sides )
2x = 120 ( divide both sides by 2 )
x = 60
Answer:
x = 60
Step-by-step explanation:
The two angles are corresponding. This means that both of the angles are congruent (same). So, you set both of them equal to each other. That means to do 2x + 15 = 135. You do basic algebra and then you get 60 for x. Hope this helps!
20$ startup fee and a $5 monthly fee write an equation in slope intercept form that models
The slope intercept form of equation that models $20 startup fee and $5 monthly fee is y = 5x +20 , y is total fee and x is number of months
What is slope intercept form?The slope intercept form of an equation is y = mx + c
where y is y coordinate, x is x coordinate, m is the slope of the line and c is y intercept.
Let the total fee after x months be y
Then y is sum of startup fee and sum of all month's fee
For x months total monthly fees = 5(x)
Therefore the total fee after x months , y = 5x +20 which is same as slope intercept form y=mx+c
when x= 0 ⇒ y = 20 , startup fee
Thus, the equation in slope intercept form is y = 5x +20 ,where y is total fee and x is number of months.
