Question

move value to the blanks the interpretation of the expression. Lacey bought tickets to use for rides at the local carnival .Each ride requires the same number of tickets.The expression 60-5x model the number of tickets Lacey has left after going on x rides. According to the model,Lacey bought______tickets and each needs_______ -5 5 12 55 60 65

Answer 1

The total number of tickets that Lacey bought can be found by plugging in x=0 into the model, since this is the total amount of tickets that Lacey has before entering a single ride:

`x=0\Rightarrow60-5x=60-5(0)=60`

On the other hand, the coefficient of x is the amount of tickets that Lacey needs for each ride. The negative sign accounts for the fact that Lacey has to give up tickets to enter the ride.

Since the coefficient of x is -5, then 5 tickets are needed for each ride.

Therefore, Lacey bought 60 tickets and each ride needs 5 tickets.
