In this problem we must translate English words into Algebraic Expressions. So we have the following English words:
The sum of a number w and 3 is less than or equal to ten
So let's do that using two steps:
Here we have two numbers w and 3. So we must makes the sum these numbers, therefore:
[tex]w+3[/tex]
The symbol for the English words less than or equal to is ≤ hence we can write these words as:
[tex]\boxed{w+3\leq 10}[/tex]
As you can see, the algebraic expression is an inequality.
