Answer:

0, 40, and 80 are the values that work for this compound inequality.
Step-by-step explanation:
To create a compound inequality, we have to examine the conditions for
to work.
Since
can not be below 0° C, that means that
must be greater than or equal to 0.
Which is represented as
, or
.
Since
can not be above 100° C, that means
must be less than 100.
Which is represented as
.
We can combine both inequalities into one, where
is shared between the two. This creates
.
Let's test each value of
.
0 is <em>equal to</em> 0 and less than 100, so it works.
40 is <em>greater </em>than 0 and less than 100, so it works.
80 is <em>greater </em>than 0 and less than 100, so it works.
120 is <em>greater </em>than 0 and <em>greater</em> than 100, so it doesn't work.
160 is <em>greater </em>than 0 and <em>greater</em> than 100, so it doesn't work.
Hope this helped!
