In mathematical expressions, a variable (a letter used to represent a certain value) represents an unknown or changeable value. It is often the variable x.
It is unknown and it usually just represented as pi. It represents the ratio between the circumference and the diameter.

Unknown Variable
The expression for eleven decreased by a number can be written as 11 - x, where x represents the unknown number being subtracted from eleven. This expression represents the operation of subtraction, where the value of x will determine the final result after subtracting from eleven.
is called a variable or a literal constant, or informally an unknown.

The phrase that describes an unknown or changeable quantity is "variable." In mathematics and science, a variable represents a value that can change depending on the conditions or inputs of a given situation. This concept is essential for equations, functions, and experiments, where the outcomes may vary.
A variable is a symbol that represents an unknown or changeable number, typically a letter such as x, y, and z.
Phrases that describe an unknown or changeable quantity include "variable," "unknown value," "indeterminate amount," and "flexible figure." Terms like "x" or "y" in mathematical contexts represent such quantities. Additionally, phrases like "subject to change" or "estimated value" convey the idea of uncertainty or variability.
Variable
The answer is variable
An unknown changeable quantity refers to a variable in mathematics or science whose value is not fixed and can vary or change under different conditions. It is often represented by symbols, such as ( x ) or ( y ), in equations or expressions. This concept is crucial for understanding relationships and functions, as it allows for the exploration of how different factors influence outcomes.

in algebra any letter really, however normally it's an x
x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
The letter that commonly represents an unknown in mathematics is "x." It is frequently used in algebraic equations to denote a variable or an unknown value that needs to be solved for. Other letters like "y" and "z" are also used, but "x" is the most widely recognized.
