C- Commutative property.
Explanation: The numbers are flipped around, but still give you the same answer!
Answer:
4 , 2, 8, 4 ..............
Positive 18, going off the assumption that the tick 2 spaces away from -1 is positive 9.
Battery is down currently = 2/5
Battery drains at the rate of 1/9 every hour.
Remaining battery life of Vera = 1 -2/5 = 3/5
Let y we the number of hours battery will last.
So, 1/9 y = 3/5
y = 27/5
y = 5 + 2/5 hours
y = 5 hrs and 24 mins
So battery will last another 5 hrs and 24 mins.
hope this helps:)
