Define mixed fraction.A mixed fraction is one that is represented by both its quotient and remainder. A mixed fraction is, for instance, 2 1/3, where 2 is the quotient and 1 is the remainder. An amalgam of a whole number and a legal fraction is a mixed fraction.
How to convert mixed fraction to improper fraction?When converting a mixed fraction to an improper fraction, the denominator and the whole number are multiplied, the product is added to the numerator, and the sum is written as the numerator and denominator.
2(5x) = 14
10x = 14
x = 14/10
Simplify the fraction, by turning it into a mixed number.
x = 1 4/10
Simplify the equation by dividing it by 2, so that it is in simplest form.
x = 1 2/5

What are 5 ways to solve problems?
The 5 ways to solve problems are identifying the problem, generating different solutions, choosing one solution, implementing the chosen solution and evaluating the result.
A problem is any type of disruption from normality that is impeding progress. A problem can be time-consuming and requires too much energy to solve it.
There are 5 different steps to solving a problem
Step 1. Identify the Problem
Step 2. Generate potential solutions
Step 3. Choose one solution
Step 4. Implement the solution you’ve chosen
Step 5. Evaluate results
Sometimes it is required to start the process entirely over. To make the problem-solving process easier, it’s best to facilitate the solution as much as possible. Try to concentrate on the solution instead of the problem. Finally, be in the correct psyche to want to change. This contains having the right mindset language, both are positive and open-minded.

What is the number of terms in the expansion of 2x 3y 2 )( 2x 3y 2 2?
The number of terms in the expansion of [tex](2x^3y^2)(2x^2y^3)[/tex] is 12.
When expanding the product of two polynomials, the number of terms in the expansion is equal to the product of the number of terms in each polynomial. In this case, the first polynomial has 1 term (2x^3y^2) and the second polynomial has 1 term (2x^2y^3), so the number of terms in the expansion will be 1*1=1.
A polynomial function is one in which the variable's non-negative integer powers or positive integer exponents are the only parts of the equation. Examples of polynomial functions include quadratic, cubic, and other equations. An example of a polynomial with an exponent of 1 is 2x+5.
However, the expression provided is not a polynomial, it is a number.

A photographer plans to frame photos that measure
7 inches long and 6 inches wide. Because his
frames are larger than the photographs, he will
make a mat of uniform width to fill the area between
the photograph and the frame.
Define a unit for each quantity in the worksheet.
Then enter a variable for the mat width and use
this variable to write expressions for the other
quantities.
A unit for each quantity in the worksheet for the mat width are 5.357 inches.
How is the area of a rectangle calculated?The size of a rectangle. A = l × b. Once the length and width are known for any rectangle, the area may be determined. The area of the rectangle is calculated as a square-unit dimension by multiplying length and width.
How do you determine the size of a rectangle frame?Add the height and the width together to get the area of a rectangle. Given that each side of a square is the same length, all you need to do to determine its area is multiply the length of one of its sides by itself.
Length = 7 inches
Width = 6 inches
Area of photograph = length width = 7 6 = 42
Total area of photograph and frame = 84
frame length ( 7 + 2x)
frame width ( 6 + 2x)
Total area = Total area of photograph and frame
( 7 + 2x) ( 6 + 2x) = 84
2 + 13x - 21 = 0

3.

9
Your answer
Step-by-step explanation:
if the question is to round 3.79 to the nearest tenth then here you go: *can't really grab you question, but....*
So, 3.79 to the nearest tenth would be 3.8
Why? How?
To round, you have to convert the farthest right value, which is 5 or higher, to one and add it to it's previous. So, 9 is higher than 5, could be 5, but can change to 1 and be added to it's previous 7 making 7 8, and that's how we get 3.8 (8 being the tenth of the decimal...hope I'm making sense. it's just the rules, how it works, and how I can explain it).
Hope you get it right and good luck :)

Answer:
6. 21.0°
7. 39.6°
8. 58.0°
9. 72.9°
Step-by-step explanation:
6. Reference angle (θ) = x°
Hypotenuse = 15
Adjacent = 14
Apply CAH:
[tex] Cos(\theta) = \frac{Adjacent}{Hypotenuse} [/tex]
Plug in the values
[tex] Cos(x) = \frac{14}{15} [/tex]
[tex] x = Cos^{-1}(\frac{14}{15}) [/tex]
x ≈ 21.0° (nearest tenth)
7. Reference angle (θ) = x°
Opposite = 19
Adjacent = 23
Apply TOA:
[tex] Tan(\theta) = \frac{Opposite}{Adjacent} [/tex]
Plug in the values
[tex] Tan(x) = \frac{19}{23} [/tex]
[tex] x = Tan^{-1}(\frac{19}{23}) [/tex]
x ≈ 39.6° (nearest tenth)
8. Reference angle (θ) = x°
Hypotenuse = 17
Adjacent = 9
Apply CAH:
[tex] Cos(\theta) = \frac{Adjacent}{Hypotenuse} [/tex]
Plug in the values
[tex] Cos(x) = \frac{9}{17} [/tex]
[tex] x = Cos^{-1}(\frac{9}{17}) [/tex]
x ≈ 58.0° (nearest tenth)
9. Reference angle (θ) = x°
Opposite = 43
Hypotenuse = 45
Apply SOH:
[tex] Sin(\theta) = \frac{Opposite}{Hypotenuse} [/tex]
Plug in the values

Part B: If the school district wants to award the school with the highest average attendance, which school should it choose and why? Justify your answer mathematically. (5 points) (10 points)
Answer:
a: School W is has the most consistent attendance
b: School W has the highest average attendance
Step-by-step explanation:
For a:
The most consistent school will be the school whose data has the smallest variance. *Consistent doesn't mean the best, it's just the least differing among it's own data. The variance tells us how spread out the data is, so the school with the smallest variance is the most consistent.
See photo 1 for the calculations of the variances of each school...
For b:
Take the mean for each school. Whichever has a higher value is the school with the highest average.
See photo 1 for the calculations if the means for each school. (the mean is used to calculate variance, so we will do this part first)

The error that Maria likely make is that she subtracted 1n from 5n.
How to infer the error?In Mathematics, it is important to note that an expression is simply used to show the relationship between the variables that are provided or the data given regarding an information. In this case, it is vital to note that they have at least two terms which have to be related by through an operator.
The value of the expression will be:
= -4n +3+9n-4
= 5n - 1
The error was because 1n was minus from 5n

Which answer would correct the error?
A. Change 5x−17 to 5x+17.
B. Change 12(2x+6) to 12(2x−6).
C. Change (x+5) to (x−5).
D. Change +4(x+5) to −4(x+5).
The Correct change to make the Equation correct is Change (x+5) to (x−5).
The Correct option is (C).
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
12(2x+6)+4(x+5)=5x−17
28x + 72= 5x-17
23x = 109
x= 4.73
First, change (2x+6) to 12(2x−6).
12 (2x - 6) + 4(x+5) = 5x- 17
24x - 72 +4x +20 = 5x- 17
28x -52 = 5x- 17
23x = 35
x= 1.52
Now, Change (x+5) to (x−5).
12 (2x + 6) + 4(x-5) = 5x- 17
24x + 72 +4x -20 = 5x- 17
28x + 52 = 5x- 17
23x = 69
