Which of the following is the solution to | X-12 K 15? O A. x<27 and x <-3
O B. x< 27
O C. x< 27 and x > -3
O D. x<27 or x>-3

C. x<27 and x>-3

Step-by-step explanation:

[x-12]<15

-15<x-12<15

-15+12<×<15+12

-3<×<27

x>-3 and x<27

30

step-by-step explanation:

times by times

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
