7. Jane is at the amusement park. The admission is $25, and the rides are $2 each. If Jane spent $57 at the amusement park, how many rides did she go on?

Jane got on 16 rides

Step-by-step explanation:

r= numbers of rides

25 + 2r

25 + 2r = 57

-25           -25

2r\2               32/2

          r=16

6.13

Step-by-step explanation:

From the question, we are informed that MUSIC Randall recorded 8 songs on his most recent CD and that the total length of the CD is 49 minutes.

The unit rate to represent the average length per song on the CD will be calculated by dividing 49 by 8. This will be:

= 49 minutes / 8

= 6.125 minutes per song

= 6.13 to nearest hundredths
