(m/(n(m-n))) + (n/(m(n-m)))
Take mn(m-n)(n-m) as a common denominator
(m(m(n-m)) + n(n(m-n))) / (mn(m-n) (n-m))
= (m(mn-m^2) + n(nm-n^2)) / ((m^2n-mn^2)(n-m))
= (m^2n-m^3+n^2m-n^3) / (m^2n^2-m^3n-mn^3+m^2n^2)
= (m^2n-m^3+n^2m-n^3) / (2m^2n^2-m^3n-mn^3)

Enter your answer in the box.
Answers
Your answer is 4.
Explanation:--
The Mean of the Data set is ---
2+5+1+7+6+4+3
7
= 4.
Hence, Mean of the data set is 4.
Answer:
To find the mean, you must add all the numbers and divide it by the amount of numbers in the set.
2 + 5 + 1 + 7 + 6 + 4 + 3
= 28
28 divided by 7 = 4
The answer is 4
Step-by-step explanation:
The arithmetic mean is the simple average, or sum of a series of numbers divided by the count of that series of numbers.
In the world of finance, the arithmetic mean is not usually an appropriate method for calculating an average, especially when a single outlier can skew the mean by a large amount.
Other averages used more commonly in finance include the geometric and harmonic mean.

If you invest $8,600 at a 3.95% simple annual interest rate, approximately how long will it take for you to have a total of $21,000? a. 25.3 years b. 36.5 years c. 45.9 years d. 60.7 years
Answers
The time taken to have a total of $21,000 is 36.5 years.
To calculate the time it takes to reach $21,000 with a simple annual interest rate, we can use the formula for simple interest:
Interest = Principal × Rate × Time
Where:
Interest is the additional amount earned on the initial investment (in this case, the difference between $21,000 and $8,600),
Principal is the initial investment ($8,600),
Rate is the annual interest rate (3.95% expressed as 0.0395),
and Time is the unknown variable we want to find.
We can rearrange the formula to solve for Time:
Time = Interest / (Principal × Rate)
Let's plug in the values:
Interest = $21,000 - $8,600 = $12,400
Principal = $8,600
Rate = 0.0395
Time = $12,400 / ($8,600 × 0.0395) ≈ 36.5
So, it will take approximately 36.5 years to have a total of $21,000.

You are shopping and see an item that is normally priced for $950 on sale for 20% off. However, you have a coupon for an additional 30% off. (The cashier will apply your coupon to the sale price, not the normal price.)
What is the final cost of the time (before sales tax) after the sale and coupon discounts?
Answers
Answer:
The final cost before sales tax is $475.
Step-by-step explanation:
you add the 30% to the 20% and that equals 50% off. Which is half off so you have to divide $950 by 2. That equals $475. Easy :)

the graph shows the number of servings in different amounts of frozen yogurt listed on a carton. Enter an equation that gives the number of servings y in x pints. Use only decimal form, if necessary.
Answers
Answer:y=2.5x
Step-by-step explanation:
We have been given a graph that shows numbers of servings (y) in different amounts (x) of frozen yogurt listed on a carton.
To write an equation that gives the number of servings y in x pints, we will have to find the slope (rate of change) of our given linear function.
Since we know that rate of change of a function can be found by vertical change of the function divided by horizontal change of the function.
m= Slope (rate of change).
=Difference between two y-coordinates.
=Difference between corresponding x-coordinates of the y-coordinates.
Upon substituting coordinates of two points (0,0) and (4,10) in slope formula we will get,
The slope of our given line is 2.5.
Now we will write equation of our given line is slope-intercept form. The equation of a line in slope-intercept form is: , where m=slope and b = y-intercept (initial value).
Upon substituting m=2.5 and coordinates of point (4,10) in slope-intercept form of equation we will get,
Upon substituting m=2.5 and b=0 in slope-intercept form of equation we will get,
Therefore, the equation will give the number of servings y in x pints.

Answers
Answer:
C
Step-by-step explanation:
The total population of Deer's in the given span area is 5852 Deer's.
What is population density?Population density is defined as the total number of humans presence
per unit square miles. Mathematically, we can write -
Population density = (Total human population)/(Total span area)
Given is that a county in north Carolina spans 532 square miles. the population density of deer in the county is 11 deer per square mile
We can write the total population of Deer's in the given span area as -
Population = Deer's population density x total area span
Population = 11 x 532
Population = 5852
Therefore, the total population of Deer's in the given span area is 5852 Deer's.

Answers
The amount of cherrries that Dahlia has in stock at the end of the day is 69.
How many cherries does Dahlia have in stock at the end of the day?The first step is to determine the number of cherries that were remaining after 19 were sold.
Cherries remaining = 22 - 19 = 3
Number of cherries in the shipment == 22 x 3 = 66
Total number of cherries at the end of the day = 66 + 3 = 69

if x= -1 and y=2 is the solution of the simultaneous equations,
ax-by= 1
ay+bx= - 7
find the value of a and b with the proper steps
Answers
Answer:
a = -3, b = 1
Step-by-step explanation:
1. Plug in the given values into the equations:
a(-1) - b(2) = 1
a(2) + b(-1) = -7
2. Isolate a in the first equation:
a(-1) - b(2) = 1 = a · -1 - b · 2 = 1
-a - 2b = 1
-a -2b+2b = 1+2b
-a = 1 + 2b
[tex]\frac{-a}{-1} =\frac{1}{-1} +\frac{2b}{-1}[/tex]
a = -1 - 2b
3. Substitute "a = -1 - 2b" in for a in the second equation:
(-1 - 2b)2 + b(-1) = -7
4. Simplify:
-2 - 4b + b(-1) = -7
-2 - 4b -b = -7
-2 -5b = -7
5. Isolate for b:
-2+2 - 5b = -7+2
-5b = -5
[tex]\frac{-5b}{-5} =\frac{-5}{-5}[/tex]
b = 1
6. Substitute the b value into an equation to solve for a:
a = -1 -2 · 1
a = -3 · 1
a = -3
