Answer:
<h2>9<n<17.</h2>
Step-by-step explanation:
9 less than a number <em>n</em> is less than 17. This verbal expression can be represented as a mathematical expression.
First, we observe that it says "9 less than", this is expressed like 9<, but less than who? it says "less than <em>n"</em>, so it would be 9<n.
In second place, the expression continues, <em>n </em>is less than 17, which is expressed like n<17.
At last, we unite both parts, and we have:
9<n<17.
