Can someone explain to me adding and subtracting mixed numbers
Answer:
1.Find the Least Common Denominator (LCD)
2.Find the equivalent fractions.
3.Add or subtract the fractions and add or subtract the whole numbers.
4.Write your answer in the lowest terms.
Step-by-step explanation:
Step-by-step explanation:
So first, you turn the mixed numbers into improper fractions. Then you change the denominators to the same number. Finally, you add or subtract.
Example:
4 1/5- 2 1/2= 21/5- 5/2=42/10-25/10=17/10=1 7/10
The parallelogram pictured below has a perimeter of 129. Find the value of y.
Answer:
y = 2½ = 2.5
Step-by-step explanation:
From the question given above, the following data were obtained:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
The perimeter of a parallelogram can be obtained by using the following formula:
Perimeter = 2(a + b)
Thus, with the above formula, we can obtain the value of y as shown below:
Perimeter = 129
Slant Side (a) = 10y – 9
Base (b) = 17y + 6
y =.?
Perimeter = 2(a + b)
Perimeter = 2a + 2b
129 = 2(10y – 9) + 2(17y + 6)
Clear bracket
129 = 20y – 18 + 34y + 12
Collect like terms
129 + 18 – 12 = 20y + 34y
135 = 54y
Divide both side by the coefficient of y i.e 54
y = 135/54
y = 2½ = 2.5
Thus, the value of y is 2½ or 2.5
2.25x=27

(5x + 1)(5x - 1)
Answer:
25x² - 1
Step-by-step explanation:
Given
(5x + 1)(5x - 1)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(5x - 1) + 1(5x - 1) ← distribute both parenthesis
= 25x² - 5x + 5x - 1 ← collect like terms
= 25x² - 1

Answer:
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
The relation R is not a function
Step-by-step explanation:
Relations and Functions
We are given the ordered pairs of a relation, let's call it R:
R={(-3, 2), (-2, 2), (1, 2), (-3, 1), (0, 3)}
The domain of R is the set of values that relate to 1 or more elements from the range.
The domain of R is {-3,-2,1,-3,0}
The range of R is: {2,1,3}
Note the value 2 is repeated in the second set, but it's reported only once as part of the Range.
A relation is a function if each element of the domain appears in only one ordered pair, or relates to a single element in the Range.
The relation R is not a function, because the ordered pairs (-3, 2) and (-3, 1)
map the element -3 twice.

Which of these terms does not describe polygon A’B’C’D?
A. Rotation
B. Transformation
C. Reflection
D. Image
The terms that does not describe polygon A’B’C’D should be considered as the option c. reflection.
What is reflection?In terms of geometry, a reflection should be known as the flip, It should be considered as the mirror image of the shape. The image should reflect via the line that we called as the reflection line.
When it should be at reflection so each and every point in the figure should be equidistant with respect to the another figure.
Hence, The terms that does not describe polygon A’B’C’D should be considered as the option c. reflection.

find the y-intercept and slope of the function’s graph, and find the equation for the function using the table in the picture.
y- intercept:
slope:
equation:
m = (y2-y1)/(x2-x1)
m = (9-5)/(3-2)
m = 4
Substitute the values in y= mx + c,
5 = (4)(2) + c
5 = 8 + c
c = -3
Thus, the equation is y= 4x -3
The y intercept is -3 and the slope of line is 4 .
Then the equation of line will be : y= 4x -3
Given,
Points on x and y axis .
Standard equation of line :
y = mx + c
m = slope of line
c = y intercept
Now
Firstly find out the slope of line ,
m = (y2-y1)/(x2-x1)\
m = (9-5)/(3-2)
m = 4
Now to calculate the value of y intercept
Substitute the values in y= mx + c,
5 = (4)(2) + c
5 = 8 + c
c = -3
Thus, the equation is m = (y2-y1)/(x2-x1)

Lin-Manuel runs a rare book store. Last year, he earned $35,000 in revenue and had explicit costs of $8,000. Lin-Manuel could have made $29,750 testing information security equipment and received an additional $10,000 if he had used the company's inputs in a different way. Calculate Lin-Manuel's economic profit.
Answer: Economic loss of $12,750
Step-by-step explanation:
Economic profit is calculated by deducting both the implicit and the explicit costs from income.
Explicit cost are the costs of running the business whilst implicit costs are the gains that could have been earned if other alternatives had been embarked on.
Economic profit (loss);
= 35,000 - 8,000 - 29,750 - 10,000
= (12,750)

Given that 2x + 1 =5, what is the value of (x+3)^3
Answer: 125
Step-by-step explanation:
First, solve for x in the first equation.
1) Subtract 1 from both sides.
2x = 4
2) Divide by 2 on both sides.
x = 2
Next, substitute the value of x into the second expression.
(2 + 3)^3
= 5^3
= 125
Answer:
The value of (x + 3)³ is 125.
Step-by-step explanation:
First, we have to find the value of x.
To do so, start with the first equation, 2x + 1 = 5.
We can easily solve this equation to find the value of x.
First, start by subtracting 1 from each side.
This leaves us with 2x = 4.
Next, divide by two on each side.
This will leave us with the answer x = 2.
Now we know the value of x = 2.
All that's left to do is substitute the value of x, 2, for x.
First, start with the second equation (x + 3)³.
We know that x is equal to 2, so we can enter 2 for x.
We then have the equation (2 + 3)³.
Next, solve.
Add the 2 and the 3 together.
Now, the equation is 5³.
5³ is equal to 5 · 5 · 5
5 · 5 · 5 = 125
To sum up,
We found out that x = 2
Using 2 for x, we found out that (x + 3)³ is equal to 125.
