can someone help please!

Answer: d

Step-by-step explanation:

r+g less than or equal to 1,200

r less than or equal to 500

The pair of inequalities models the number of  tickets that can be sold is r + g ≤ 1200 and r ≤ 500

Let r represent the number of reserved seats and g represent the number of seats for general  admission.

Since the school has 1,200 concert tickets for sale, hence:

r + g ≤ 1200   (1)

Also, there are at most 500 reserved-seat tickets. Hence:

r ≤ 500  (2)

The pair of inequalities models the number of  tickets that can be sold is r + g ≤ 1200 and r ≤ 500

Answer:

x = 18

Step-by-step explanation:

The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{80}{80+2x}[/tex] = [tex]\frac{60}{60+27}[/tex] = [tex]\frac{60}{87}[/tex] ( cross- multiply )

60(80 + 2x) = 6960 ← divide both sides by 60

80 + 2x = 116 ( subtract 80 from both sides )

2x = 36 ( divide both sides by 2 )

x = 18

Answer:

Option D is the correct answer...

X - 23 = 18

According to the answer

We have to add 23 to both sides

X - 23 + 23 = 18 +23

X = 41

Answer:

A translation simply moves the graph, or pre-image, without changing the size or spinning the image. A reflection flips the pre-image across some line. A rotation spins the pre-image around a point. A dilation either expands or shrinks the pre-image.

Step-by-step explanation:

Hope this helps

Transformation involves changing the size, the position and the location of a shape.

When a shape is dilated, the size of the shape is altered to form a new shape

When a shape is translated, the shape is moved across the coordinates, but the size remains unchanged

When a shape is reflected, the shape is flipped across the coordinates, but the size remains unchanged

When a shape is rotated, it must be rotated across a point, and the size remains unchanged

The above means that translation, reflection and rotation are rigid transformation, while dilation is not.

Answer:

x = 12 degrees

Step-by-step explanation:

This isosceles triangle has two equal sides and thus two equal angles.  We find the measure of angle 2 by subtracting 76 degrees from 180 degrees, and then dividing the result (104 degrees) by 2:  m<2 = 52 degrees.

Then m<2 = 52 degrees = 3x + 16, or

                    52 degrees - 16 degrees = 3x, or:

                     36 degrees = 3x

Thus, x = 12 degrees

-45 - 9n = -81

-9n = -81 + 45

-9n = -36

n = -36/-9

n = 4

Hope this helps you. :)

Answer:

4=n

Step-by-step explanation:

-81= -45-9n

+45   +45

-36= -9n

÷ -9     ÷-9

4= n

substitute:

-81= -45 -9 (4)

-81= -45 -36

-81= -81

Answer:

x=-5

Step-by-step explanation

The first box has eight x's and six 1's which means that it would be written as 8x+6

The second box has four x's and fourteen -1's which means that it would be written as 4x-14

You set them equal to one another

8x+6=4x-14

You subtract 4x from both sides

4x+6=-14

Subtract 6 on both sides

4x=-20

Divide 4 on both sides

x=-5

Answer:

216

Step-by-step explanation:

I'm sure there is a simpler way to do this but this is how I did it.

First divide 18 by 6 because it triples every 6 hours.

18/6=3

This means it will triple three times

Then triple the value three times

#1. 8x3=24

#2. 24x3=72

#3. 72x3=216

In 18 hours the virus will infect 216 people.

Answer:

o travel 650 miles the bus will need 26 gallons of gas.

Step-by-step explanation:

First we find how many miles travel the bus on one gallon of gas:

300/12=25 miles.

Second we find how many gallons will it need to travel 650 miles:

650:25=26 gallons of gas.

Answer:

3.5

Step-by-step explanation:

The constant rate of proportionality, k, is expressed as [tex]k = \frac{y}{x}[/tex], and shows that two quantities are proportional to each other. In this logic, rearranging this in terms of y gives us:

[tex]y = kx[/tex]

Thus we can determine that k is 3.5, in this case.

The number of ways he can distribute 4 ones into 5 groups is 120 ways.

Permutation has to do with the arrangement. For instance, to distribute "r" values into "n" groups, this can be calculated as:

Hence for you to distribute 4 ones into 5 groups, we will use the formula above to have:

5P4 = 5!/(5-4)!

5P4 = 5!/1!

5P4 = 5!

5P4 =120 ways

Hence the number of ways he can distribute 4 ones into 5 groups is 120 ways.

Answer:

Part A: x = 4.

Part B: The answer normally would be x = 12, but since your question asked why it has no real solution, it is because the solution (x=12) does not make the equaion true. Why? Because the value given from the equation that should make the equation true does not relate the equation in itself; hence making it have no solution.
