7. if i' is the midpoint of su, what are st. tv and su?
6.3
3x +27

Your answer would be 8. You can drop the 2 because it is less than 5, so you cannot round up. You drop the nine and raise the 6 to a 7. So then it becomes 7.7 You then take the second 7 and round your number up to 8. So your final answer should be 8.
