Suzie paid $324 for a number of tickets (t) to a rock festival. Which expression represents the cost of each ticket?

324/t

Step-by-step explanation:

Suzie paid $324 for t tickers into the rock festival.

The price of each ticket is therefore the total she paid divided by the number of tickets that was bought:

= Total cost / Number of tickets

Total cost = $324

Number of tickets = t

Expression therefore is:

= 324/t

Answer

5 and -4

Explanation

If the two triangle are congruent then they have the same area.

20 = x² - x

x² - x - 20 = 0

x² - x + (1/2)² = 20 + (1/2)²

(x - 1/2)² = 20.25

x - 1/2 = √20.25

x - 1/2 = 4.5                             or    x - 1/2 = - 4.5

x = 4 1/2 + 1/2                                      x = -4 1/2 + 1/2

   = 5                                                      = -4

The values of x are 5 and -4.
