Mitch's salary increases by $10,000 but he has to repay $2,000 for his loan. Therefore, he ends up with an extra $8,000 per year.
Explanation:Mitch receives a 25% increase on his previous pay of $40,000 which equates to an additional $10,000 for the year (25% of $40,000 is $10,000), giving him a new salary of $50,000.
However, Mitch must pay 4% of his new salary towards his Study Assist loan. 4% of $50,000 equals $2,000. So he must repay $2,000 for his loan.
Therefore, the extra pay that Mitch actually keeps after paying his loan is $10,000 (rise in salary) minus $2,000 (loan repayment) which is $8,000 for the year. He ends up with $8,000 extra compared to his initial salary.

Please Help!! find the solution of this system of equations 2x - 2y= -38 -5x - 4y= 23
y = 72.
Solving the System of Equations
To find the solution of the system of equations given by 2x - 2y = -38 and -5x - 4y = 23, we can use the method of elimination or substitution. In the method of elimination, we can multiple the first equation by 2 to make the coefficients of y the same, which would give us 4x - 4y = -76. Then, we could add this new equation to the second given equation (-5x - 4y = 23) to eliminate the y variable:
4x - 4y = -76 (First equation multiplied by 2)
-5x - 4y = 23 (Second given equation)
Adding these equations together, we get:
-1x + 0y = -53
or simply
-x = -53, from which x = 53.
Next, we can substitute x back into either of the original equations to solve for y. For example, using 2x - 2y = -38:
2(53) - 2y = -38
106 - 2y = -38
-2y = -38 - 106
-2y = -144
y = 72
Therefore, the solution to the system of equations is x = 53 and y = 72.

how much chocolate with each person get if 3 people share 1/2 lb of chocolate equally
solve the equation 5.25x+6=74.25
In Andrew’s Furniture Shop, he builds bookshelves and tables. Each type of furniture takes him about the same time to make. He figures he has time to make at most 18 pieces of furniture by this Saturday. The materials for each bookshelf cost him $20.00 and the materials for each table cost him $45.00. He has $600.00 to spend on materials. Andrew makes a profit of $60.00 on each bookshelf and a profit of $100.00 for each table. How many of each piece of furniture should Andrew make to maximize profit?
Andrew should determine the number of bookshelves and tables to make by using linear programming to solve for the variables given the constraints of his time, material costs, and profits. The optimal solution lies where the constraints intersect within the feasible region.
The student inquired about how many bookshelves and tables Andrew should make in order to maximize profit, given the constraints of time, material cost, and the profit from each item sold. This is a typical problem that can be solved using linear programming, a method in mathematics to achieve the best outcome given a series of linear constraints.
First, let us define two variables: x for the number of bookshelves and y for the number of tables. The constraints given by Andrew's situation are:
x + y \<= 18 (time constraint to make the furniture)
20x + 45y \<= 600 (cost constraint for materials)
Profit function to maximize: P = 60x + 100y
To maximize the profit P, we need to solve for x and y within the given constraints. After setting up the equations, we can graph the constraints and find the feasible region. The solution will be at a vertex of the feasible region, given by the intersection of the constraints. Andrew can use methods like the graphical method, the simplex method, or an algebraic method to find the optimal numbers of bookshelves (x) and tables (y) to maximize his profit.

what is the value of x if 46=6x-2
The product of two consecutive even positive integers is 674 more than the sum of the two integers. Find the integers.
The equation is A ( A + 2 ) = 674 + ( A + ( A + 2 ) )
The first integer is A = 26
The second integer is B = 28
What is an 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.
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 data ,
Let the two numbers be A and B
where , the first integer is = A
The second integer is = B
B is the consecutive integer of A , so
The value of B = A + 2
Now , the equation will be
The product of two consecutive even positive integers is 674 more than the sum of the two integers
So , substituting the values in the equation , we get
A ( A + 2 ) = 674 + ( A + ( A + 2 ) )
On simplifying the equation , we get
A² + 2A = 674 + 2A + 2
Subtracting 2A on both sides of the equation , we get
A² = 674 + 2
A² = 676
Taking square roots on both sides of the equation , we get
A = 26
The value of B = A + 2
B = 28
Therefore , the value of A = 26
The value of B = 28
Hence ,
The first integer is A = 26
The second integer is B = 28

Solve the formula for the perimeter of a rectangle with width w and length l,for the length P=2w+2l solve for l
Answer:
[tex]l=\frac{P}{2}-w[/tex]
Step-by-step explanation:
we know that
The formula for the perimeter of a rectangle is equal to
[tex]P=2(w+l)[/tex]
where
l is the length
w is the width
Solve for l
That means ----> Isolate the variable l
Divide by 2 both sides
[tex]\frac{P}{2}=\frac{2(w+l)}{2}[/tex]
Simplify right side
[tex]\frac{P}{2}=w+l[/tex]
Subtract w both sides
[tex]\frac{P}{2}-w=w+l-w[/tex]
Simplify right side
[tex]\frac{P}{2}-w=l[/tex]
Rewrite
[tex]l=\frac{P}{2}-w[/tex]
Answer:Solve P = 2l + 2w for w.
The first step is to isolate the variable term, 2w.

133=x + (x+5) + (x+14)
133 = 3x+19
3x=114
x= 114/3 =38
5+38 =43
38+14 =52
check: 38 +43 +52 = 133
3 sides are : 38, 43 & 52
Indicate, in standard form, the equation or inequality that is shown by the graph. (0,4)(4,0)
Answer:
standard form y = -x + b.
Step-by-step explanation:
Given : Graph and points (0,4)(4,0).
To find : Standard form of equation .
Solution : We have given that points (0,4)(4,0).
Let [tex]x_{1}[/tex] = 0 , [tex]x_{2}[/tex] = 4
[tex]y_{1}[/tex] =4 , [tex]y_{2}[/tex] = 0.
Slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
Plugging values
Slope = [tex]\frac{0 - 4}{4 - 0}[/tex].
Slope = -1 .
Standard form y = m x + b
y = -1 x + b.
Plug (0,4)
4 = -1 ( 0)+ b
4 = b .
Now , plugging values b= 4 , m = -1.
y = -x + b.
Therefore, standard form y = -x + b.

How can you use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages?
To fit data to a normal distribution and estimate population percentages, calculate the mean and standard deviation for the data set, use these values to construct a normal distribution, and apply the empirical rule and confidence intervals to estimate population percentages.
Explanation:To use the mean and standard deviation of a data set to fit it to a normal distribution and estimate population percentages, you will need to understand key statistical principles such as standard deviation, the mean, and the normal distribution curve.
Mean and Standard Deviation
The mean, which is an average of all the values in a data set, provides a central value. The standard deviation represents the spread of the data around this mean. A lower standard deviation indicates that the values are closer to the mean, while a higher standard deviation indicates a wider spread.
Fitting Data to a Normal Distribution
A normal distribution, also known as a bell curve, shows how values in a data set are dispersed around the mean. The properties of the normal distribution (68% of data within 1 standard deviation of the mean, 95% within 2 standard deviations, and 99.7% within 3 standard deviations) are known as the empirical rule or the 68-95-99.7 rule.
Estimating Population Percentages
To estimate population percentages using the mean and standard deviation, you construct a confidence interval. This range provides an estimate of where you expect the true population parameter to lie with a certain level of confidence. For example, a 95% confidence interval means that you can be 95% confident that the true population mean lies within this interval.
