The three consecutive positive integers satisfying the statement are

9, 10, and 11.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Let, The three numbers be n, (n + 1), and (n + 2).

Therefore, the numerical expression of the given statement is,

2(n)(n + 2) + 2 = 20(n + 1)

2n² + 4n + 2 = 20n + 20.

2n² - 16n - 18 = 0.

n² - 8n - 9 = 0.

n² - 9n + n - 9 = 0.

n(n - 9) + 1 (n - 9) = 0.

(n - 9)(n + 1) = 0.

n = 9 is the positive integer.

So, The numbers are 9, 10, and 11.

what is the question ?

without an actual question I can only "daydream" things about this information.

EB is the diameter, FB is therefore the radius.

since FB = 3 units, EB = 2×FB = 2×3 = 6 units.

the arc angle AB = 120°.

if you need to express the angle in radians, remember :

360° (the full circle) = 2pi

120° = 360/3 = 2pi/3

the arc angle AE is the supplementary angle to AB (both together have 180° or 2pi/2 = pi).

180 = AB + AE = 120 + AE

AE = 180 - 120 = 60°

60° = 360/6 = 2pi/6 = pi/3

the arc angle BC = 45°.

45° = 360/8 = 2pi/8 = pi/4

the arc angle CD = 30°

30° = 360/12 = 2pi/12 = pi/6

the arc angle ED is the supplementary angle to BC and CD.

180 = ED + BC + CD = ED + 45 + 30 = ED + 75

ED = 180 - 75 = 105°

105° = pi - pi/4 - pi/6 = 12pi/12 - 3pi/12 - 2pi/12 = 7pi/12

the sum of

AB + BC + CD = 2pi/3 + pi/4 + pi/6 =

= 4×2pi/12 + 3pi/12 + 2pi/12 =

= 8pi/12 + 3pi/12 + 2pi/12 = 13pi/12

Answer and Step-by-step explanation:

Let's call the angle between the roads on the south side "y" for simplicity. Since the two roads intersect, the sum of the two adjacent angles on one side must add up to 180 degrees. Therefore, we can set up an equation:

y + 69 = 180

Solving for y, we get:

y = 180 - 69 = 111

We also know that y is equal to 3x, so we can set up another equation:

3x = 111

Solving for x, we get:

x = 37

Therefore, the value of x is 37.

[tex]2x+2y=-8 \implies x+y=-4 \implies y=-4-x[/tex]

We can substitufe this result into the second equation.

[tex]-10x-5(-4-x)=-5 \\ \\ -10x+20+5x=5 \\ \\ -5x+20=5 \\ \\ -5x=-15 \\ \\ x=3 \implies y=-4-3=-7[/tex]

On solving the provided question, we can say that the area of the picture of the flyer in the newspaper is = 36 square inches.

The size of an area on a surface can be expressed as an area. The area of an open surface or the boundary of a three-dimensional object is referred to as the surface area, whereas the area of a planar region or planar region refers to the area of a form or planar layer. The total amount of space filled by a planar (2-D) surface or shape of an object is known as its area. Draw a square on a piece of paper using a pencil. a character with two dimensions. The area of a shape on paper is the space it takes up. Imagine that the square is composed of more compact unit squares.

he original flyer has an area of = 576 square inches.

The Picture Noah prints will be a dilation of the flyer using a scale factor of 1/4.

Scale factor k=1/4

So the area of the picture of the flyer in the newspaper is

By solving the equation 510 = 2(6x + 11x), we know that the length of the given rectangle is 90 units.

It primarily consists of a variable, sometimes with a numerical constant in addition.

Take the following illustration into consideration to quickly grasp this idea. 3x – 4 = 5. It is a simple equation of class 7.

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

So, we know that the ration is 6:11 and the perimeter is 510 units.

Then, form and solve the equation as follows:

510 = 2(6x + 11x)

510 = 12x + 22x

510 = 34x

x = 510/34

x = 15

Then, the length will be:
6x

6(15)

90 units

Therefore, by solving the equation 510 = 2(6x + 11x), we know that the length of the given rectangle is 90 units.

Answer:

The slope: 4

Y-intercept: 9

m = the slope

b = y-intercept

In this case y = 4x + 9

m = 4

b = 9

So,

The slope: 4

Y-intercept: 9

Answer:

Slope: 4/1 or 4

Y-Intercept: 9

Step-by-step explanation:

y = mx + b is the Slope Intercept Formula. 'm' in the formula stands for rate of change in y/x, which is practically slope. 'b' in the formula is where the line crossed the y line. It's where it intercepts with y.

He must sell 520 units from the second shipment in order to have sold 80 percent of all of the unit.

This is mathematical equations.

The salesman sold 75% of 800 units, so he sold 0.75 * 800 = 600 units from the first shipment.

The salesman wants to sell 80% of all the units, which is a total of 0.80 * (800 + 600) = 0.80 * 1400 = 1120 units.

To find out how many units he must sell from the second shipment, we subtract the number of units he has already sold from the number of units he wants to sell:

1120 units - 600 units = 520 units.

Therefore, the salesman must sell 520 units from the second shipment in order to have sold 80% of all the units.

Answer:

Step-by-step explanation:

You need to find the LCD of 12 16 and 20

Using Prime Factorization:

     12 = 2 * 2          * 3

     16 = 2 * 2 * 2 * 2

    20 = 2 * 2               * 5      

            2    2   2   2  3   5                  so LCD will be 2 * 2 * 2 * 2 * 3 * 5= 240

so she will need    240 / 12 = 20 packs of pencils

                               240 / 16 = 15  packs of notebooks

Answer:

y = 3(2)^x

Step-by-step explanation:

If we look at the x and y values, we see that the xs' increase by 1 each time, while the ys' double (12*2 = 24, 24 *2 = 48 etc.).

Because the value doubles each time, we know that this is an exponential equation, and the base (b) is 2.

The general form (as shown) is y = a(b)^x, where a is the initial value (y-intercept or value of y when x = 0) and b is the base.

We can find a by plugging in one x and y coordinate and 2.

For example, we can use (1, 6) to solve for a:

[tex]y=a(b)^x\\6=a(2)^1\\6=a(2)\\3=a[/tex]

Answer:

(10, 24)

Step-by-step explanation:

First equate both the equations,

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

Then expand the brackets,

2x + 4 = 4x - 16

Collect like terms in each sides,

4 + 16 = 4x - 2x

Simplify and solve,

20 = 2x

20 ÷ 2 = x

x = 10

Then substitute 10 for x in one of the equations,

y = 2(x + 2)

y = 2(10 + 2)

y = 24

Therefore, the point of interssection is (10, 24).

you can solve this using the simultaneous equation

so y = y

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

4x - 16 = 2x +4

4x - 2x = 4+16

2x/2=20/2

therefore x=10

y=2 (x+2)

y=2(10+2)

y=2(12)

y=24

The equivalent expression of 4/5a + 2/3b + 1/8 - 7/6b - 3/4 - 2/5a is 136/120a + 107/120b.

One common way to simplify an expression is to use the unitary method, which involves finding a common denominator and then canceling out like terms.

In this case, we'll use the unitary method to find an equivalent expression to 4/5a + 2/3b + 1/8 - 7/6b - 3/4 - 2/5a.

To start, we'll find a common denominator for all the terms in the expression.

The least common multiple of 5, 3, 8, 6, and 5 is 120. Now, we can convert all the fractions to have a denominator of 120.

Next, we'll simplify each term by dividing the numerator and denominator by their greatest common factor.

96/120a can be simplified to 8/10a by dividing both the numerator and denominator by 8. 80/120b can be simplified to 2/3b by dividing both the numerator and denominator by 40. And so on.

Finally, we'll rearrange the terms and simplify them using the unitary method. We'll start by canceling out like terms, which have the same variable and the same sign.

So, 8/10a and 96/120a are both positive and have the variable a, so we can simplify them to 104/120a.

Similarly, we can simplify 2/3b and 105/120b to 107/120b. We'll then add up all the positive terms and subtract all the negative terms.

The final equivalent expression is

=> 104/120a + 107/120b + 15/120 - 90/120

=> (104 + 107 + 15 - 90)/120a + (107/120)b

=> 136/120a + 107/120b.
