Solve the compound inequality.
1.n<2 or 2n3>5.
2.2c4>6 and 3c+1<13
Are these the answer?
1.n<2 or n>4.
2.1<c<4.

1. No. n>2 and n>4 , which is n>4
2. correct 
Did you divide the n by itself and then 2 by n in order to get the sign reverse?
Also could you help me on this one? Thanks
A number minus one is at most nine, or two times the number is at least twentyfour.
Is it n1</= 9 or 2n =/> 24 which equal n>/= 12 or n </= 10? 
I divided by 1, which reversed the inequality.
yes on the second.
