Toby purchased 5 tickets online for a show. The tickets cost $12 each plus there was a $3.50 service fee for the order. Which expression represents how much money Toby spent for the tickets?

5(12) + 3.50

Step-by-step explanation:

There are 5 tickets that cost 12 dollars each so you multiply. Then you add 3.50 because of the fee

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
