system of equations: n=2/3 ,a=14,x=−9
for each thing: x= −9  | a= 14  | n= 2/3

1. x = -9

2. a = 14

3. n = [tex]\frac{2}{3}[/tex]

1. Rearrange Terms

61 = 7 - 6x

61 = -6x + 7

2. Subtract 7 from both sides

61 = -6x + 7

61 - 7  = -6x + 7 - 7

3. Simplify

Subtract the numbers:

61 - 7 = -6x + 7 - 7

54 = -6x + 7 - 7

Subtract the numbers:

54 = -6x + 7 - 7

54 = -6x

4. Divide both sides by the same factor

54 = -6x

[tex]\frac{54}{6}[/tex] = [tex]\frac{-6x}{-6}[/tex]

5. Simplify

Divide the numbers:

[tex]\frac{54}{6}[/tex] = [tex]\frac{-6x}{-6}[/tex]

-9 = [tex]\frac{-6x}{-6}[/tex]

Cancel terms that are in both the numerator and denominator:

-9 = [tex]\frac{-6x}{-6}[/tex]

1. Combine multiplied terms into a single fraction

[tex]\frac{3}{2}[/tex]a - 26 = -5

[tex]\frac{3a}{2}[/tex] - 26 = -5

2. Find common denominator

[tex]\frac{3a}{2}[/tex] - 26 = -5

[tex]\frac{3a}{2}[/tex] + [tex]\frac{2(-26)}{2}[/tex] = -5

3. Combine fractions with common denominator

[tex]\frac{3a}{2}[/tex] + [tex]\frac{2(-26)}{2}[/tex] = -5

[tex]\frac{3a+2(-26)}{2}[/tex] = -5

4. Multiply the numbers

[tex]\frac{3a+2(-26)}{2}[/tex] = -5

[tex]\frac{3a - 52}{2}[/tex] = -5

5. Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{3a - 52}{2}[/tex] = -5

2 · [tex]\frac{3a - 52}{2}[/tex] = 2(-5)

6. Cancel multiplied terms that are in the denominator

2 · [tex]\frac{3a - 52}{2}[/tex] = 2(-5)

3a - 52  = 2(-5)

7. Multiply the numbers

3a - 52 = 2(-5)

3a - 52 = -10

8. Add 52 to both sides

3a - 52 = -10

3a - 52 + 52 = -10 + 52

9. Simplify

Add the numbers:

3a - 52 + 52 = -10 + 52

3a = -10 + 52

Add the numbers:

3a = -10 + 52

3a = 42

10. Divide both sides by the same factor

3a = 42

[tex]\frac{3a}{3}[/tex] = [tex]\frac{42}{3}[/tex]

11. Simplify

Cancel terms that are in both the numerator and denominator:

[tex]\frac{3a}{3}[/tex] = [tex]\frac{42}{3}[/tex]

a = [tex]\frac{42}{3}[/tex]

Divide the numbers:

a = [tex]\frac{42}{3}[/tex]

a = 14

a = 14

1. Divide the numbers

4 = n  + [tex]\frac{-10}{-3}[/tex]

4 = n + [tex]\frac{10}{3}[/tex]

2. Subtract [tex]\frac{10}{3}[/tex] from both sides

4 = n + [tex]\frac{10}{3}[/tex]

4 - [tex]\frac{10}{3}[/tex] = n + [tex]\frac{10}{3}[/tex] - [tex]\frac{10}{3}[/tex]

3. Simplify

Subtract the numbers:

4 - [tex]\frac{10}{3}[/tex] = n + [tex]\frac{10}{3}[/tex] - [tex]\frac{10}{3}[/tex]

[tex]\frac{2}{3}[/tex] = n + [tex]\frac{10}{3}[/tex] - [tex]\frac{10}{3}[/tex]

Subtract the numbers:

[tex]\frac{2}{3}[/tex] = n

Move the variable to the left:

[tex]\frac{2}{3}[/tex] = n

n = [tex]\frac{2}{3}[/tex]

n = [tex]\frac{2}{3}[/tex]

Persons cannot be in decimals we can expect about 9 passengers will not keep their reservation.

Given,

In the question:

An airline finds that about 8 percent of the time, a person who makes an advance reservation does not keep the reservation.

Therefore, for each of their 105105105-passenger planes, the company schedules 113113113 people with advance reservations.

Now, According to the question:

Capacity of the airline per trip = 105 only

But company schedules = 113 people with advance reservations

Since 8% do not turn up

Out of 113 passengers who reserved in advance we can say

that 8% of 113 passengers will not keep their reservation

Based on this information, number  of the scheduled people will not keep their reservation

= 8% x 113

= 0.08*113

=9.04

Hence, Persons cannot be in decimals we can expect about 9 passengers will not keep their reservation.

Answer:

Step-by-step explanation:

The slope of a linear function is a measure of the rate at which the value of the function changes as the input (x) changes. A slope of -5/3 means that for every 3 units of change in the input, the output (y) changes by -5 units.

In general, a negative slope indicates that the graph of the function is decreasing. As the input increases, the output decreases. A slope of -5/3 is a relatively steep negative slope, which means that the graph of the function will have a steep downward slope.

A slope of -5/3 also tells us that the function is not a horizontal line. A horizontal line has a slope of 0, which means that the output does not change as the input changes. A slope of -5/3 is not equal to 0, which means that the function is not a horizontal line.

Overall, the slope of a linear function tells us about the direction and steepness of the graph of the function. A slope of -5/3 indicates that the graph of the function is decreasing and relatively steep.

The image for  Triangle QRM  is attached below

Generally, To construct a quadrilateral PQRS with the given dimensions, you can use a straightedge and a compass. Here is a step-by-step guide:

To construct a triangle QRM with an area equal to quadrilateral PQRS, you can use the same method as above. Here is a step-by-step guide:

To verify that the area of triangle QRM is equal to the area of quadrilateral PQRS, you can use the formula for the area of a triangle:

Area of triangle QRM = (1/2) * QM * QR * sin(angle QRM)

And the formula for the area of a quadrilateral:

Area of quadrilateral PQRS = (PQ * QR * sin(angle PQR))/2

Substituting the given values and solving for sin(angle QRM), we find that:

sin(angle QRM) = (2 * area of quadrilateral PQRS)/(QM * QR)

= (2 * (5 * 5.5 * sin(75)))/(5 * 5.5)

= sin(75)

Thus, the area of triangle QRM is equal to the area of quadrilateral PQRS, as desired.

Rounded to the nearest percent, the markup is approximately 55%.

What is the percent markup?

Markup percentage is calculated by dividing the gross profit of a unit (its sales price minus its cost to make or purchase for resale) by the cost of that unit.

To find the percent markup, you can use the following formula:

percent markup = (retail price - wholesale price) / wholesale price * 100

Plugging in the values given, we have:

percent markup = (98.50 - 63.55) / 63.55 * 100 = 34.95 / 63.55 * 100 = approximately 55%

What is clap ?

Gonorrhea is known by the slang term "the clap." Gonorrhea is also referred to as "the drip." Someone who has an may feel stigmatized and shamed by these words.

On a shared plane, parallel lines do not cross one another. Now, if a transversal crosses two parallel lines at two separate sites, four angles are created at each location. The characteristics of parallel lines with respect to transversals are therefore listed below.

The pair of alternative internal angles are equal when two parallel lines are crossed by a transversal.

When a transversal cuts between two parallel lines, the interior angles on the same side of the transversal are additional.

In the problem angle

a = [tex]119^{o}[/tex]

e = [tex]66^{o}[/tex]

Now , c = e ( alternate angles, interior)
