Question 903903
Ideally you post them as seperate questions, so please keep that in mind in the future. 


# 1


3y >= 4


y >= 4/3 ... Divide both sides by 3.


=======================================================


# 2


x/2 < 6


x < 6*2 ... Multiply both sides by 2.


x < 12 


=======================================================


# 3


M/5 > -5 


M > -5*5


M > -25


=======================================================


# 4


c/-10 <= -2 


c >= -2*(-10) ... Take note of the sign flip


c >= 20



The sign flips when you multiply or divide both sides by a negative number


=======================================================


# 5


8n > -1


n > -1/8
