Questions: A constant is . . . a variable a number a math or science mystery a letter

Solution Steps

The question seems to be asking for the definition of a constant in a mathematical context. A constant is typically a fixed value that does not change. In this context, it is most accurately described as a number.

In mathematics, a constant is a value that does not change. It is a fixed number that remains the same throughout a given problem or equation. Constants are often represented by numbers, such as \( \pi \) or \( e \), which have specific, unchanging values.

Given the options provided:

• A constant is not a variable, as variables can change.
• A constant is not a math or science mystery, as it has a specific definition.
• A constant is not a letter, although letters can represent constants in equations.

The most accurate description of a constant is that it is a number.
