Answer: n > 6.85
Step-by-step explanation: So the orignal question was 13 < 4n – 14.4 and you want to know how to solve it.
13 < 4n – 14.4
27.4 < 4n (You add 14.4 to both sides to get n by itself)
27.4/4 < 4n (You divide both sides by 4 to get just n)
6.85 < n (This is because 27.4/4 is 6.85)
I hope this helps
