Question 1208299
<pre>
No fair dumping a whole bunch of problems on us like that!
Here's the first one.  Maybe someone else will do some others.</pre>
 1 Write the following in set notation:

(a) The set of all real numbers greater than 27.<pre>
{x|x &epsilon; R, x > 27}</pre> 
(b) The set of all real numbers greater than 8 but less than 73.<pre>
[Note: "it is greater than 8" is the same as saying "8 is less than it"]: 

{x|x &epsilon; R, 8 < x < 73}
