here we rest to find a number such that
negative 20 is less than that number at
the same time that number has to be less
than negative 10 let's look at these
numbers on a number line okay so
negative 20 I'll put a dot right there
at that number and negative 10 I'll put
a dot at that number another way to
think of this is that the number that
we're looking for has to be greater than
negative 20 also at the sign same time
less than negative 10 okay so looking on
our number line certainly anything in
between negative 20 and negative 10
should solve that so answers are going
to vary you could choose any number in
there let's go with negative 15 another
way to think of this is that negative 20
is less than negative 15 and at the same
time negative 15 is less than negative
10
