The value of n is 1/2 and it is not an even number or odd number

From the question, the steps are given as

n + n + 1 = 2n + 1

n + n + 1 = 2n+2-1

n + n + 1 = 2(n+1) -1

Also, from the question, we have the result of the expression to be

2

This means that

n + n + 1 = 2

Substitute n + n + 1 = 2(n+1) -1 in the equation n + n + 1 = 2

So, we have

2(n + 1) - 1 = 2

Add 1 to all sides of the equation

So, we have

2(n + 1) = 3

Divide both sides of the equation by 2

So, we have

n + 1 = 3/2

Subtract 1 from all sides

n = 1/2

The above implies that the number n is neither an even number, nor an odd number

This is so because the result is a fraction

Value of x is 28.5 and y is 14.

An angle is a figure in Euclidean geometry made up of two rays that share a terminal and are referred to as the angle's sides and vertices, respectively. Angles created when two rays are in the plane where the rays are located. The intersection of two planes also creates angles. We refer to these as dihedral angles.

Given Data

a = 2x + 3y

b = 4x - y

c = 3x + 2y

∠b = 100° ( corresponding angle)

4x - y = 100

4x - 100 = y

∠a = ∠b ( alternate angle)

2x + 3y = 4x - y

Equating values of y

2x + 3(4x - 100) = 4x - 4x + 100

2x + 12x - 300 = 100

14x = 400

x = [tex]\frac{400}{14}[/tex]

x = 28.5

For the values of y,

Answer:

x = 9

Step-by-step explanation:

To solve for x, you must isolate the variable.

First, start by adding 2 to BOTH sides to eliminate the 2.

3=1/3x. then divide each side by 1/3

3÷1/3 = x

3/1 × 3/1 = x

Answer: $13,713.75

Step-by-step explanation: 10% of $13,250 = $1,325 (the raise given)

$13,250 - $1,325 = $11,925 (original salary)

15% of $11,925 = $1,788.75

$11,925 + $1,788.75 = $13,713.75

The weight of the twelve people on the elevator is 1,825 pounds.

And the weight of the thirteen person is given by the inequality:

x ≤ 175

We have an elevator with 12 people in it, such that the weights of these 12 people are:

175, 140, 135, 155, 170, 190, 125, 160, 150, 150, 130, 145

To find the total weight we just need to add these numbers, we will get:

175 + 140 + 135 + 155 + 170 + 190 + 125 + 160 + 150 + 150 + 130 + 145 = 1,825

So the 12 people in the elevator have a total weight of 1,825 pounds.

Now, the weight limit is 2,000 pounds.

So if we define x as te weight of the 13 th person, we can write the inequality:

1,825 + x ≤ 2,000

x ≤ 2,000 - 1,825

x ≤ 175

So the person can weight at mos 175 pounds.

The equation of the line that has a slope of -3 and passes through the point (5, -1) is 3x + y = 14.

What is slope ?

A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.

We know the slope point form,

y - y1 = m( x - x1 )

Where x1 and y1 atre the coordinates of the points and m is the slope.

Putting thew values from the question:

y - (-1) = -3 ( x - 5)

=> y  + 1 = -3x + 15

Answer:

1) 54+2x=5x−6−18x Distributive Property

2) 60=−15x Division Property of Equality

3) −4=x Division Property of Equality

Explanation:

1.) This answer is Distributive Property because the parenthesis in the original equation were removed through the process of distributing.

3(–2 – 6x) was distributed by multiplying 3 • –2 and 3 • –6x to get –6 – 18x

2.) This answer is Division Property of Equality because for all real numbers x, y, and z, if x = y and z ≠ 0, then x/z = y/z. This is true in this equation because of 60/–15 = −15x/–15.

3.) Division is used to get the value of x, which is –4.

For the first function, the coordinates of A are (0, 1).

The equation of circle B is (x -4)^2 + y^2 = 25

And the circle intercepts the x-axis at:

(9, 0) and (-1, 0)

We have the equation:

y = a^x

And we know that A is the y-intercept of that equation, remember that the y-intercept is the point such that x = 0, so the y-coordinate will e:

y = a^0 = 1

So the y-intercept (point A)  is the point (0, 1).

We start with the circle:

x^2 + y^2 = 25

And we apply a translation of 4 units to the right, so we write this as:

(x - 4)^2 + y^2  = 25

c) The circle intercepts the x-axis when y = 0, then:

(x - 4)^2 + 0^2 = 25

x - 4 = ±√25

The amount of money that Ahmed gave to his brother is AED 140.

It is given in the question that Ahmed has AED 180. He gives his brother 0.7  with bar notation of the amount he has.

We have to find the amount given by Ahmed to his brother.

Here, we have to convert a non-terminating but recurring rational number into fraction form.

Let 0.7 bar = x

Multiplying the equation by 10, we get

7.7 bar  = 10x

10x - x = 7.7 bar - 0.7 bar

9x = 7

x = 7/9

Dividing 36 by the difference between product of 3 and 6 and the square root of 36 gives 3.

The problem asks us to divide 36 by the difference between the product of 3 and 6 and the square root of 36.

First, we need to find the product of 3 and 6, which is 18.

Then, we need to find the square root of 36, which is 6.

So, the difference between the product of 3 and 6 and the square root of 36 is 18 - 6 = 12.

Therefore, we need to divide 36 by 12.

We can do this by performing long division, or by using the calculator.

If a cave explorer is at an elevation of −32 feet and the explorer starts moving at a rate of −6 feet per minute. it will take, 9 in minutes for the explorer to reach an elevation deeper than −140 feet.

Elevation of feet =  −32 feet.

Feet per minute =  −6 feet per minute

Elevation deeper than  feet = −140 feet

Let x  represent the time for reach the desired height

Inequality

-32 - 6x = ≤ -140

Substract 32 from both side

12x ≤ 140 -32

12x  ≤ 108

NO. Your friend is incorrect because the solution to the system of equations on the graph is: (4, 3).

The solution to a system of linear equations is the coordinates of the point where the two lines of the linear equations intersect.

The x-coordinate and the y-coordinate of this point lie on each of the lines of the linear equations. This means that, both values of x and y are a solution to each of the linear equation given.

Therefore, the solution to a system of linear equations is usually represented as (x, y) and not just as a single value of x.

The system of linear equations that is graphed above shows that both lines intersect at (4, 3), that is, when x = 4, the value of y = 3.

We are told that  5 apples and 3 pears costs 8p more than 3 apples and 5 pears.

Let the cost of apples be x and let the cost of pears be y. Thus, the equation that represents the sentence is;

5x + 3y = 3x + 5y + 8

Rearrange to get;

5x - 3x + 3y - 5y = 8

2x - 2y = 8

No. there is no rigid transformation taking Rectangle A to Rectangle B. See the explanation below.

The type of transformation that is taking place in the attached image from Rectangle A to Rectangle B is a non-rigid transformation. This is is because A rigid transformation (or isometry) is a transformation that DOES NOT change the size or shape of a geometric figure.

As it is easily observed, rectangle A is no longer the same shape and size as B. This means that the change or transformation that has occurred is non-rigid.

It is to be noted that dilation is a transformation that keeps the figure's geometry and orientation but alters its size. A dilation's scale factor is the factor by which each linear measure of the figure (such as a side length) is multiplied.
