: A theater sells tickets for a concert. Adult tickets sell for $6.50 each, and children's tickets sell for $3.50 each. The thea
BARSIC [14]

Answer: 321 adult tickets and 227 children tickets were sold.

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of children tickets that were sold.

The total number of tickets that the theatre sold is 548. This means that

x + y = 548

Adult tickets sell for $6.50 each, and children's tickets sell for $3.50 each. The total ticket sales was $2881. This means that

6.5x + 3.5y = 2881 - - - - - - - - - - -1

Substituting x = 548 - y into equation 1, it becomes

6.5(548 - y) + 3.5y = 2881

3562 - 6.5y + 3.5y = 2881

- 6.5y + 3.5y = 2881 - 3562

- 3y = - 681

y = - 681/ -3

y = 227

x = 548 - y = 548 - 227

x = 321

Step-by-step explanation:

a^2+b^2=c^2

x is the hypotenuse (c). You can find the hypotenuse by finding the opposite of the right angle

48^2+20^2=2304+400=2704

I don’t get it it doesn’t make sense
san4es73 [151]

Answer:

Area of A = 32ft

Area of B = 36ft

Step-by-step explanation:

All you need to do to solve is multiply width * length * height.

If you do so,

Area of A = 3 * 2 * 5 1/3

= 6 * 16/3

= 32

Area of B = 6 * 4 * 1 1/2

= 24 * 3/2

= 36

Hope this helps!!

Let me know if I'm wrong or you need help in any other problem!!
