Answer:
7
Step-by-step explanation:
135 = 15*(x+2)
so i am sure you know that 1 hour is sixty minutes
so this is how it woulds
10/1 * 60/1 = 600 minutes
so that means that 10 hours would be equal to 600 minutes
then add on the 39 minutes
639
BUT WAIT there are the seconds
24/1 * 1/60 = 0.4
so 24 seconds is 0.4 (40%) of a minute
so it would take 639.4 minutes for saturn to make a full rotation
i hope this helped and please vote me for brainliest! have a nice day!
