A. c+2=c+3
Never. C is a constant value. Adding different values to a constant value will never be equal.

B. 4+2p=4-2p
Sometimes. If p=0 this is true, but not in any other circumstances.

C.2(x+5)+1=2x+11
2x+10+1=2x+11

Each year the seventh graders who study life science participate in a special field trip to the city zoo in 2010 the school paid
juin [17]

Answer:

Yes, the price the school pays each year in entrance fees is proportional to the number of students entering the zoo

Step-by-step explanation:

Relationships between two variables is proportional if their ratios are equivalent.

In 2010, the school paid $1,260 for 84 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = 1260:84=15:1

In 2011, the school paid $1,050 for 70 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = 1050:70=15:1

In 2012, the school paid $1,395 for 93 students to enter the zoo.

Ratio of the price the school pays each year in entrance fees to the number of students entering the zoo = 1,395:93=15:1

As 1260:84=1260:84=1,395:93=15:1,

the price the school pays each year in entrance fees is proportional to the number of students entering the zoo.

The school that Mary goes to is selling tickets to a spring musical. On the first day of ticket sales
andrezito [222]

Answer:

The cost of one adult ticket is $13, and the price of one student ticket is $4.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the cost of an adult ticket

y is the cost of a student ticket.

6 adult tickets and 1 student ticket for a total of $82

This means that

6x + y = 82

y = 82 - 6x

The school took in $51 on the second day by selling 3 adult tickets and 3 student tickets.

This means that

3x + 3y = 51

Simplifying by 3

x + y = 17

Since y = 82 - 6x

x + 82 - 6x = 17

-5x = -65

5x = 65

x = \frac{65}{5} = 13

y = 82 - 6x = 82 - 6*13 = 82-78 = 4

The cost of one adult ticket is $13, and the price of one student ticket is $4.
