The sophmore class at south high school raised $800 from ticket sales for the dance. Tickets sold for $1.50 pre - sale, and $2.00 at the door. If a total of 475 tickets were sold how many tickets were sold at the door?

Answers

Answer:

So they sold 300 tickets in advance and 175 tickets at the door.

Step-by-step explanation:

Answer:

175 tickets were sold at the door.

Step-by-step explanation:

Let x = number of pre-sale tickets.

Let y = number of tickets sold at the door.

Equation for total number of tickets:

x + y = 475

Equation of total price of tickets:

1.5x + 2y = 800

System of equations:

x + y = 475

1.5x + 2y = 800

Solve the first equation for x:

x = 475 - y

Substitute into second equation.

1.5(475 - y) + 2y = 800

712.5 - 1.5y + 2y = 800

0.5y = 87.5

y = 175

Answer: 175 tickets were sold at the door.

Answers

Answer:

75 students are going. 15 adults are going.

Step-by-step explanation:

Since the question says there are 90 tickets in total, 75 student ticket plus 15 adult tickets equals 90 tickets in total. Also 75 divided by 15 is 5, which suits the ratio of 5 students to per adult.

Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3

Answers

Ccccccccccccccccccccc

The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.

What is the equation?

More than one variable may be present inside a linear equation.

An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

As per the given equation,

13 = -3 + z

Since, A + B = B + A

Thus, -3 + z can be written as z - 3

So, 13 = z - 3

Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".

Which of these graphs is the solution set for the equation y = -3x - 2?

Answers

A because y=-3x-2 has these transformations
The negative before the 3 means the slope is going down
The 3 means it goes 3 down every time it goes right one, the number before the x is the slope and slope is rise over run, 3 = 3/1 so it would normally mean it goes up 3 every time it goes right one but because the 3 is negative it means the line goes down
The negative two at the end moves the line down two, if it were plus two the line would go up two, the number in this spot is what determines the vertical translation

Put it all together and you get the line has goes down 3 every time it goes right one and crosses the y axis at -2

P.S. wouldn't mind getting brainliest

Answer:

Step-by-step explanation:

Frist you find negative 2 and you can see that 2 are going there so you need to find where negative 3 is when you add negatives they trun into a possitve so go up 3 times from negative 2.

Answer:

solved the solution incorrectly and graphic their solution correctly.

Step-by-step explanation:

this is because if 4x + 1<= -4

the next step will be to subtract 1 from both sides.

BUT if their solution is x<= 2, they objectively graphed it correctly
