Write down the inequality for x that is shown on this line.

There were about 483 principals in attendance.

The correct option is (3).

The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.

As per the given data:

The total number of people in the recent conference = 650

The total number of people in one exhibit room = 70

Number of teachers in one exhibit room = 18

Number of principals in one exhibit room = 52

To find out the total number of exhibit rooms:

= Total number of people in the conference / total people in one room

= 650 / 70

= 9.28 = 9 {rounding off to the nearest integer}

Number of principals in one exhibit room = 52

Total number of principals in the conference:

= Number of rooms × Principals in one room

= 9 × 52 = 468 which is equal to 483 {approximate answer}

There were about 483 principals in attendance.

Hence, There were about 483 principals in attendance.

Answer:

(-1,2.5) is on the line.

(11,10) is on the line.

(70,40 is not on the line.

(-2, 1.875) is on the line.

Step-by-step explanation:

First, find the equation of the line.  Two write an equation in the slope -intercept form of the line we need a slope and the y-intercept.  We can find this from the 2 points given (-5,0) and (3,5).  The ordered pair is written in the from (x,y)  The first number is how much we move right or left from the origin (0.0) and the second number tells us how much we move up or down from the origin (0,0).

To find the slope, we find the change in y over the change in x.

[tex]\frac{(5-0)}{3 - -5)}[/tex] = [tex]\frac{5}{3+ 5}[/tex] = [tex]\frac{5}{8}[/tex]  Now we can use either of the points to find the y-intercept.  Let's use (3,5)

slope = [tex]\frac{5}{8}[/tex]

x = 3

y =5

y=mx + b plug in what we know

5 = [tex]\frac{5}{8}[/tex](3) + b  This is the same as writing

5 = [tex]\frac{5}{8}[/tex][tex](\frac{3}{1})[/tex]      3 and [tex]\frac{3}{1}[/tex] mean the same thing

5 = [tex]\frac{15}{8}[/tex] + b  Now subtract [tex]\frac{15}{8}[/tex] from both sides of the equation

[tex]\frac{5}{1}[/tex] - [tex]\frac{15}{8}[/tex] = [tex]\frac{15}{8}[/tex] - [tex]\frac{15}{8}[/tex] + b

[tex]\frac{40}{8}[/tex] - [tex]\frac{15}{8}[/tex] = b

[tex]\frac{25}{8}[/tex] = b  Now we can write the equation

y = mx + b

y = [tex]\frac{5}{8}[/tex] x + [tex]\frac{25}{8}[/tex]

N ow that we have the equation, we can plug in the (x,y) and see if the equation is true or not.  If the equation is true, the point is on the line.

(-1,2.5)

y = [tex]\frac{5}{8}[/tex] x + [tex]\frac{25}{8}[/tex]

2.5 = [tex]\frac{5}{8}[/tex](-1) + [tex]\frac{25}{8}[/tex]

2.5 = [tex]\frac{-5}{8}[/tex] + [tex]\frac{25}{8}[/tex]

2.5 = [tex]\frac{20}{8}[/tex]

2.5 = 2.5

Yes, point (-1, 2.5) is on the line.

(11,10)

y = mx + b

10 = [tex]\frac{5}{8}[/tex](11) + [tex]\frac{25}{8}[/tex]

10 = [tex]\frac{55}{8}[/tex] + [tex]\frac{25}{8}[/tex]

10 = [tex]\frac{80}{8}[/tex]

10 = 10

Yes, point (11,10) is on the line.

(70,40)

y = mx + b

40 = [tex]\frac{5}{8}[/tex](70) + [tex]\frac{25}{8}[/tex]

40 = [tex]\frac{350}{8}[/tex] + [tex]\frac{25}{8}[/tex]

40 = [tex]\frac{375}{8}[/tex]

40 ≠ 46.875

Point  (70,40) is not one the line.

(-2, 1.875)

y = mx + b

1.875 = (-2)[tex]\frac{5}{8}[/tex] + [tex]\frac{25}{8}[/tex]

1.875 = [tex]\frac{-10}{8}[/tex] + [tex]\frac{25}{8}[/tex]

1.875 = [tex]\frac{15}{8}[/tex]

1.875 = 1.875

Point (-2, 1.875) is on the line.

The result of the simplified expression in this problem is given as follows:

D. 15.

The expression for this problem is defined as follows:

2³ + 6/3 - (-10/2)

The parenthesis takes precedence, hence:

2³ + 6/3 - (-5) = 2³ + 6/3 + 5

The power takes precedence, hence:

8 + 6/3 + 5

Division has higher precedence than addition, hence:

8 + 2 + 5.

Hence the result is given as follows:

8 + 2 + 5 = 15.

Answer:

x = 50

Step-by-step explanation:

The interior angle at each vertex of regular octagons are 135°.

3(50) - 15 = 135

For the polygon to be an 8 sided regular polygon like you said, the angle must equal 135, and so x must equal 50.

The required value of the x in the given expression is 50°.

Given that,
A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.

A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of polygons, equilateral triangles, squares, pentagons, etc

Here,
For the octagon,
The angle of a vertex is 135°.
Equating the angles,
3x  -15 = 135
3x = 135 + 15
3x = 150
x = 50

Thus, the required value of the x in the given expression is 50°.

The ∠LPM is supplementary to ∠MPN.

If two angles in geometry sum up to 180 degrees, they are considered to be supplementary angles. For instance, A and B are referred to as supplementary angles if ∠A + ∠B = 180°. When combined, supplementary angles always make a straight angle (180 degrees).

Given:  
Five angles all with common vertex of P, with angle NPI measuring 55.6 degrees, angle IPK measuring 44.2 degrees, angle KPL measuring 80.2 degrees, angle LPM measuring 55.6 degrees, and angle MPN measuring 124.4 degrees

We have to find the angle which is supplementary to the ∠MPN.

Let, x be the angle supplementary to the ∠MPN.

So,

x + ∠MPN = 180

x = 124.4 = 180

x = 180 - 124.4

x = 55.6

Therefore, ∠LPM is supplementary to ∠MPN.
