x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
A variable is a single letter that represents a number. For example x is a variable.An algebraic expression can contain variables, numbers, mathematical symbols, etcetera. An example of an algebraic expression is 3x+12.
The number is called the coefficient of the variable
The term for replacing a variable with another value or expression is "substitution."
It is a poorly worded question. Any number in an expression can be a numerical variable.
The answer is B+9 for apex you are welcome and have a good day
x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
Your variable (a number) X, minus 100. X - 100

If the variable x represents the number: 5x + 3ParenthesesExponentsMultiplyDivideAddSubtractAlways remember this
A variable is a letter that represents a number. An expression that contains at least one variable is called variable expression, also called algebraic expression. A variable expression has one or more terms. A term is a number, a variable, or a product of numbers and variables. For example,3(x^2)y + 2xy + x - 7 is a variable expression, where you have 4 terms.When working with variable expression, you often use the substitution principle:If a = b, then a may be replaced by b in any expression.The set of numbers that a variable may be represent is called replacement set, or domain, of the variable. To evaluate a variable expression, you replace each variable with one of its values and simplify the numerical expression that results.Example: Evaluate the expression 2x - 4y for x = 5 and y = -9.Solution:2x - 4y= 2(5) - 4(-9)= 10 + 36=46
That looks like the description of an EXPRESSION. However, an expression need not have "at least one operation"; a single number, or variable, is a perfectly valid expression.
