We rewrite the inequality so that it matches the left side of the "then" part.

a)By adding 8 to each side, we have: x+8>5+8

x+8>13

So, insert>.

b)Multiply both sides by -5. Recall that when we multyply of divide both sides of an inequality by a negative number, we change the direction of the inequality: -5x<-15

Add 18 to both sides: -5x+18<3

So, insert <.

Let's say that I have two ordered sets of numbers $\{1,2\}$ and $\{3,4\}$. I'm trying to figure out the number of possible ways to combine these two sets into one without breaking the ordering of the two sets.

So for instance, $\{1,2,3,4\}$, $\{3,4,1,2\}$, and $\{1,3,2,4\}$ are valid combinations, but $\{2,1,4,3\}$ isn't. How do I figure out the number of valid combinations? This feels like something I should remember from college, but I'm drawing a blank. It feels somewhere in between a combination and a permutation.
