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.

Answer:

  1. 48°
  2. 60°
  3. 72°

Step-by-step explanation:

The sum of ratio units is 4+5+6 = 15, so each unit stands for 180°/15 = 12°. Multiplying the ratio units by 12° gives the angle values:

  4×12° : 5×12° : 6×12° = 48° : 60° : 72°

Angles 1 to 3 are 48°, 60°, 72°, respectively.
