I'll do the first three, and the absolute value problem, to give you an idea on how to do these


#1
-6%3E4y Start with the given inequality

-6%2F4%3Ey Divide both sides by 4


-3%2F2%3Ey Reduce

So the answer is y%3C-3%2F2





#2


8-u%3E4 Start with the given inequality


-u%3E4-8Subtract 8 from both sides


-u%3E-4 Combine like terms on the right side


u%3C%28-4%29%2F%28-1%29 Divide both sides by -1 to isolate u (note: Remember, dividing both sides by a negative number flips the inequality sign)



u%3C4 Divide

--------------------------------------------------------------
Answer:
So our answer is u%3C4





#3



5w%3E-6w%2B11 Start with the given inequality


5w%2B6w%3E11 Add 6w to both sides


11w%3E11 Combine like terms on the left side


w%3E%2811%29%2F%2811%29 Divide both sides by 11 to isolate w



w%3E1 Divide

--------------------------------------------------------------
Answer:
So our answer is w%3E1





#4




abs%282h%2B1%29%3C5 Start with the given inequality


Break up the absolute value (remember, if you have abs%28x%29%3C+a, then x+%3E+-a and x+%3C+a)

2h%2B1+%3E+-5 and 2h%2B1+%3C+5 Break up the absolute value inequality using the given rule


-5+%3C+2h%2B1+%3C+5 Combine the two inequalities to get a compound inequality



-6+%3C+2h+%3C+4 Subtract 1 from all sides


-3+%3C+h+%3C+2 Divide all sides by 2 to isolate h



----------------------------------------------------

Answer:

So our answer is

-3+%3C+h+%3C+2
