Lol do your own work. Pay attention in class, it'll pay off ;)
The average of 5, 7, 12, and 12, is (5 + 7 + 12 + 12)/4.
(5 + 7 + 12 + 12)/4 = 36/4 = 9.
The average is 9.
(h-3k)/2k=-3/4
h-3k=-6k/4
4h-12k=-6k
-12k=-6k-4h
-6k=-4h
Solution: k=2/3h
I hope I helped you with your solution! If you could give me brainliest, I would be very thankful!
