Represent the following sentence as an algebraic expression, where “a
number” is the letter .
A number is tripled.

When we say “a number is tripled,” we are essentially multiplying that number by 3. So, if we let “a number” be represented by the letter , the algebraic expression for this would be .

Now you can use that expression in equations or inequalities, or even apply it to real-life scenarios! For instance, if you have a budget represented by and you want to triple that amount for a big purchase, you would just calculate to see how much you’ll have to spend.

Feel free to get creative with your algebraic expressions, and remember that the beauty of mathematics is in the stories you can tell with them!
