Answer:
x= 31 degrees
Step-by-step explanation:
A triangle's angles add up to 180 degrees. Look at the 123, it's not part of the triangle. Subtract it from 180. You should get 57 degrees. Now, make an equation. You know it equals 180, so you add up all the sides like this: 57+92+x=180. After solving the equation, you should get 31 degrees.
Answer: number your dividing by on the outside of the symbol then the number you are dividing under the symbol.

Answer: 125 student tickets and 350 adult tickets were sold.
Step-by-step explanation:
Let x represent the number of student tickets that were sold.
Let y represent the number of adult tickets that were sold.
A concert manager counted 475 ticket receipts the day after a concert. This means that
x + y = 475
The price for a student ticket was $13.50, and the price for an adult ticket was $15.00. The register confirms that $6,937.50 was taken in. This means that
13.5x + 15y = 6937.50 - - - - - - - - 1
Substituting x = 475 - y into equation 1, it becomes
13.5(475 - y) + 15y = 6937.50
6412.5 - 13.5y + 15y = 6937.50
- 13.5y + 15y = 6937.50 - 6412.5
1.5y = 525
y = 525//1.5 = 350
x = 475 - y = 475 - 350
x = 125
OK now let's plug in the numbers.
