The zoo is hosting a special evening event for visitors ages 12 and up. During the event, the price of popcorn is reduced from $3 per bag to $2 per bag. If 843 bags of popcorn were sold during the event, which integer expresses the total amount of money the zoo lost by reducing the price?

−$843

−$1

−$2

Answers

Answer: -$843

Step-by-step explanation:

843 x 3 = $2529

843 x 2 = $1686

2529 - 1686 = $843

The zoo makes $2529 on a regular night, but because there is a discount, they make $1686. The amount of money is the difference between the two totals. Therefore, the total amount of money the zoo lost by reducing the price is $843.

843

Because the difference was 1, just do -1x843 to get -843

Answers

Answer:

5x + 15y =20 = - 3x +25y =75

= 8 minutes

Step-by-step explanation:

5x + 15y =20 multiply all by 3 to get 15x

15x +45y=60

- 3x +25y =75 multiply all by -5 to get 15x

15x -125y = -375

rewrite ans together

15x +45y=60

15x -125y = -375

-80y = -315

y = -315/ - 80

y = 3.9375 = y= 4 substitute to find x

5x + 15(4 )=20

5x +60 = 20

5x=-40

x= -40/5

x=-8

15x +45(4)=60

15x +180 =60

15x =-120

x=-8

To find the value of x for which the line passing through points F(3-2x, 12) and G(x + 9, 7) is vertical, we need to determine when the slope of the line is undefined.

The slope of a line can be calculated using the formula:
slope = (change in y-coordinates)/(change in x-coordinates)

In this case, the change in x-coordinates is (x + 9) - (3 - 2x), which simplifies to 4x + 6.
The change in y-coordinates is 7 - 12, which is -5.

For a vertical line, the slope is undefined, which means the change in x-coordinates must be zero. Therefore, we set 4x + 6 = 0 and solve for x:

4x + 6 = 0
4x = -6
x = -6/4
x = -3/2

So, the value of x for which the line passing through points F(3-2x, 12) and G(x + 9, 7) is vertical is x = -3/2.

you are completely right please follow your heart <3

It’s actually D.

You have to look at both x and y and it’s power. You have to look for the lowest power for x and y. For y as you can see that the lowest power is 2. As for x it can be either power of 3 or even 2. When you removed x^2 and y^2 from the equation. The inside parenthesis will be x^2-3xy. Just remember when you divide both x^2 and y^2, you subtract the power.

When you get the answer, please check the answer if it’s the same as the original. Meaning distribution both x^2 and y^2 to inside parenthesis. And for the power, you add them. This way you can double check and see if it’s the same.

A group of 24 students spent 1,296 minutes studying for an upcoming test. What prediction can you make about the time it will take 150 students to study for the test?

It will take them 174 minutes.
It will take them 2,592 minutes.
It will take them 8,100 minutes.
It will take them 8,745 minutes.

Answers

Answer:

It will take them 8,100 minutes.

Step-by-step explanation:

If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)

150 x 54 minutes = 8,100 minutes.

It will take them 8,100 minutes.

Answer:

x=8

Step-by-step explanation:

We first simplify both sides of the equation so it turns out like this:

(5x+x) + (3+4) =55

6x+7=55

Then we subtract 7 from both sides:

6x+7-7=55-7

6x=48

From there we divide both sides by 6:

6x/6=48/6

x=8

Answer:es 8

S tep-by-step explanation:

5x+ 3 + x + 4 =55

6x= 55-7

6x= 48

x= 8

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?

Answers

To determine whether Keira's statement is correct, we need to analyze the information provided.

According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.

If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.

However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.

Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

in order to know if Keira has two tickets left, we need to know the first number of tickets without that number there is no way to find the remainder

i need help with prob #2 on this

Answers

Answer:

x and y are not in direct variation.

Step-by-step explanation:

Direct Variation

Two variables x and y have a direct proportion or variation if:

y = k.x

Where k is the factor of proportionality. The value of k must be constant for every ordered pair (x,y). If only one of them does not have the very same k, then the relationship is not direct.

The value of k can be solved from the equation:

$\displastyle k=\frac{y}{x}$

Let's substitute the given points in the table:

(2,8)

$\displastyle k=\frac{8}{2}=4$

k = 4

(4,16)

$\displastyle k=\frac{16}{4}=4$

k = 4

(6,30)

$\displastyle k=\frac{30}{6}=5$

k = 5

Since the value of k is not constant, then x and y are not in direct variation.
