Question 1024311
 Label each statement as true or false. If false, correct the equation 
If |n + 9| <_ 4 then n + 9 >_ -4 and n + 9 <_4
Ans: -4<= n+9 <=4; true
---------------------------- 
If y - x < 5 -x then y<5
Add x to both sides to get y < 5; true
-------------------------------- 
If 3 |r+2| > 9 then r + 2 > 3 or r + 2 < -3 
r+2 < -3 or r+2 > 3 ; true
---------------------------
If 9 > -3w - 51 > 60 then -3 < w + 17 < - 20
Add 51 along the line to get:
60 > -3w > 111
Divide thru by -3 to get::
-37 < w < 20
