Answer:</h2>
In this problem we must translate English words into Algebraic Expressions. So we have the following English words:
<em>The sum of a number w and 3 is less than or equal to ten</em>
<em />
So let's do that using two steps:
<h3>
1. The sum of a number w and 3:</h3>
Here we have two numbers w and 3. So we must makes the sum these numbers, therefore:

<h3>
2. The sum of a number w and 3 is less than or equal to ten:</h3>
The symbol for the English words less than or equal to is ≤ hence we can write these words as:

As you can see, the algebraic expression is an inequality.
