#16:  Let's clear the fraction on the way to solving this inequality for x.  By mult. the given inequality by 2, we'll get -2 (is greater than) x+4.  We want x to be positive.  So, leave it where it is.  Subtract 4 from both sides of this inequality.  We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6.  What would the graph of that simple inequality look like?
Graph it.  (Hint:  The graph is a straight dashed line, and you must shade one side of it, but not the other side.

They are left with 0.51 pounds of clay. 
Step-by-step explanation:
Given, 
Amount of clay bought = 3.8 pounds
Amount used by Martha = 
Amount used by Martha = 
Amount left after Martha's use= Total amount - amount used by Martha
Amount left = 3.8 - 0.95 = 2.85 pounds
Amount used by Scott = 
Amount used by Scott = 
Amount used by Scott = 1.14 pounds
Amount left after Scott's use = Amount left after Martha's - Amount used by Scott
Amount left after Scott's use = 2.85 - 1.14 = 1.71 pounds
Amount used by Alison = 1.2 pounds
Amount left = Amount left after Scott's use - Amount used by Alison
Amount left = 1.71 - 1.2 = 0.51 pounds
They are left with 0.51 pounds of clay.

Step-by-step explanation:
b+133=180
b=180-133
b=47
a+71+40=180
a+111=180
a=180-111
a=69
c+64=180
c=180-64
c=116
140=d+47
140-47=d
d=93
e+47+47=180
e+94=180
