The correct answer is C = 9.
Step by step:
Subtract 12 - 9 = 3
3 + 9 = 12.
It’s that simple. Hold this helps!
The value of c is 9 makes the equation true.
It is given that the equation 12 - 9 + c =12.
It is required to find the value of c that makes the equation true.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
We have a linear equation in one variable:
12 - 9 + c = 12
-9 + c =0 (subtract 12 on both sides)
c = 9 ( add 9 on both sides)
Thus, the value of c is 9 makes the equation true.

Answer The Question Being Asked:
Topic: Applying Systems of Equations
Define your variables:
At Manny's taco shop, you can get an order of chips and two tacos for $9.25. The cost for two orders of chips and five tacos is $21.75.
x = Chipsy = TacosWrite your system of Equations:You can get an order of chips and two tacos for $9.25.
1 Chips + 2 Tacos = 9.25
x + 2y = 9.25The cost for two orders of chips and five tacos is $21.75.
2 Chips + 5 Tacos = 21.75
2x + 5y = 21.75Solve The System:First equate the coefficient - in this case x:
(x + 2y = 9.25) * 2 = 2x + 4y = 18.50
2x + 4y = 18.50
2x + 5y = 21.75
Minus the equations from each other to remove the coefficient you equated:
(2x + 5y) - (2x + 4y) = 21.75 - 18.50
(2x - 2x) + (5y - 4y) = 21.75 - 18.50
y = 3.25Answer The Question Being Asked:What is the cost of an order of chips?1 Taco = $3.25
y = 3.25
Substitute this into the equation.
x + 2y = 9.25
x + (2 * 3.25) = 9.25
x + 6.50 = 9.25
Rearrange to find x:
x = 9.25 - 6.50
x = 2.75
Chips = $2.75
$2.75For St. Patrick's day, Mrs. G's sixth grade class was given a choice of four different drinks. One quarter of the class chose green milkshakes, one third of the class chose green ginger ale, one eighth of the class chose the green milk and one sixth of the class chose green juice. How many students did not have a drink?
Answer:
1/8 of the number of students
Step-by-step explanation:
1/4 + 1/3 + 1/8 + 1/6 =
= 6/24 + 8/24 + 3/24 + 4/24
= 21/24
= 7/8
7/8 of the class chose drinks.
1 - 7/8 = 8/8 - 7/8 = 1/8
That means that 1/8 did not have a drink.
Since we don't know the number of students in her class, we cannot tell the number of students who did not have a drink, but we do know it is 1/8 of the number of students.

What is the difference between 8x3 – 2x2 + 5x – 7
and 5x3 – 3x2 – 2x + 4?
Answer:
First polynomial minus the second polynomial:
3 x³ + x² + 7 x - 11.
Step-by-step explanation:
The question asks for the difference between the two cubic polynomials (maximum power of x is three.) As the other answerer mentioned, the question doesn't say anything about the value of x. In that case, the difference between the two polynomials will still be a polynomial about x.
The power x in the difference can be as high as three. Assume that to be a cubic polynomial.
? x³ + ? x² + ? x + ?.
What are the values of each coefficient?
For example, the coefficient in front of x³ in the difference is the difference between the coefficients of x³ in the two original polynomials.
The coefficient of x³ in the first polynomial 8 x³ - 2 x² + 5 x - 7 is 8.The coefficient of x³ in the second polynomial 5 x³ - 3 x² - 2 x + 4 is 5.Subtract the second coefficient from the first. 8 - 5 = 3. In other words, 3 is the value of the x³ coefficient in the difference.
3 x³ + ? x² + ? x + ?.
Repeat this step for the x² and x coefficients.
x²: -2 - (-3) = -2 + 3 = 1.x: 5 - (-2) = 5 + 2 = 7.3 x³ + x² + 7x + ?.
The constant in the difference is the difference between the two constants.
-7 - 4 = -11.
Hence the difference:
3 x³ + x² + 7x - 11.
Alternatively, group the terms by the power of x:
(8 x³ - 2 x² + 5 x - 7) - (5 x³ - 3 x² - 2 x + 4)
= (8 x³ - 5 x³) + (-2 x² + 3 x²) + (5 x + 2 x) + (-7 - 4)
= 3 x³ + x² + 7 x - 11.

What expression is equivaltent to 4(2x+1)-(-6x)
Answer:
14x + 4
Step-by-step explanation:
An equivalent expression is an expression which is equal. It can be a simplified form or expanded form. Here lets simplify by using the distributive property.
4(2x+1) - (-6x)
8x + 4 + 6x
14x + 4
This is the simplified equivalent form. It can also be written in expanded form as 2(7x + 2).

A set of data has a high-value outliner. How do you expect the standard deviation to change when the outliner is removed? Would the result be different if the data had a low-value outliner instead? Explain
Answer:
type in decreased|TA i promise it will work
Step-by-step explanation:
trust bro trust
{decreased|TA}
In short, any high or low value outlier affect the data set the same way. When the outlier is removed, the standard deviation decreases.
Given that, a set of data has a high-value outliner.
What is an outliner?In simple terms, an outlier is an extremely high or extremely low data point relative to the nearest data point and the rest of the neighboring co-existing values in a data graph or dataset you're working with. Outliers are extreme values that stand out greatly from the overall pattern of values in a dataset or graph.
When you have an outlier that is higher then the bulk of the data, the standard deviation is larger then it would be without the outlier. If the outlier was lower than the bulk of data, then the standard deviation would again be larger then it would be without the outlier and the mean would go down when the outlier is removed. Where it differs is the fact that removing the outlier would result in an increase of the mean instead of a decrease.
Therefore, in short, any high or low value outlier affect the data set the same way. When the outlier is removed, the standard deviation decreases.

Final answer:
The greatest common factor of the expressions [tex]16m^6n^4[/tex], [tex]4m^3n^5[/tex], and [tex]2m^5n^3[/tex] is [tex]2m^3n^3[/tex].
Explanation:
The question is asking for the greatest common factor (GCF) of the three algebraic expressions provided: [tex]16m^6n^4[/tex], [tex]4m^3n^5[/tex], and [tex]2m^5n^3[/tex]. To find the GCF, we need to determine the highest powers of m and n that divide evenly into all three expressions.
For the variable m, the smallest exponent is 3 (in the term [tex]4m^3n^5[/tex]). For the variable n, the smallest exponent is 3 (in the term [tex]2m^5n^3[/tex]). Therefore, the GCF is [tex]2m^3n^3[/tex].
