A. If you can get 51 members of the math club, how much will the 51 t-shirts cost? b. If you only have 5 members (sad! ), how much will EACH t-shirt cost?

c. You end up with 30 members who want to buy a t-shirt. You want to sell the
shirts and end up making $100 profit for an end-of-year party. How much
should you sell each shirt for?

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3

(3x-8) or (3x+8)

step-by-step explanation:

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
