The Frenchtown Roller Rink charges a $5.50 entrance fee and a $3 hourly rate for roller skating. Which equation represents the relationship between the hours, x , and the total cost, y ? A. y = 5.50x + 3
B. y = 3x + 5.50
C. x = 3y + 5
D. x = 5.50y + 3

Solve the system by the elimination method. 3x - 2y - 7 = 0 5x + y - 3 = 0 to eliminate y, the lcm is 2. which of the following is the resulting equations? 1.3x - 2y - 7 = 0 5x + y - 3 = 0 2.3x - 2y - 7 = 0 -10x - 2y + 6 = 0 3.3x - 2y - 7 = 0 10x + 2y - 6 = 0
