Okay Thanks !

You're welcome.

I learned that constant is a number on it's own.

Right. So the constant in your problem is 7.

To find the constant in the expression 3m + 7, we need to understand what a constant is. In mathematics, a constant is a value that does not change. It stays the same regardless of any variables or unknowns involved. In this expression, 3m represents a term with a variable (m), which can vary based on its value.

The constant, on the other hand, is a term that does not have a variable. In this case, the constant is the term 7. It does not have any variables attached to it, and thus remains fixed at the value of 7. So, in the expression 3m + 7, the constant is 7.
