The school that darryl goes to is selling tickets to a choral performance on the first day of ticket sales the school sold nine adult tickets and six students ticket for a total of $165 the school took $105 on the second day by selling three adult tickets and 12 student tickets what is the price of each one adult ticket and student ticket

the price of one adult ticket is $15

the price of one student ticket is $5

Step-by-step explanation:

Let x represent the price of one adult ticket.

Let y represent the price of one student ticket.

On the first day of ticket sales, the school sold nine adult tickets and six students ticket for a total of $165. This means that

9x + 6y = 165 - - - - - - - - -1

The school took $105 on the second day by Selling three adult tickets and 12 student tickets. This means that

3x + 12y = 105 - - - - - - - - - 2

Multiplying equation 1 by 3 and equation 2 by 9, it becomes

27x + 18y = 495

27y + 108y = 945

Subtracting, it becomes

- 90y = - 450

y = - 450/- 90

y = $5

Substituting y = 5 into equation 1, it becomes

9x + 6 × 5 = 165

9x + 30 = 165

9x = 165 - 30 = 135

x = 135/9 = $15

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.
