What is a number in front of the variable?
A number in front of a variable is called a coefficient. It represents how many times the variable is multiplied. For example, in the expression (3x), the number 3 is the coefficient of the variable (x). Coefficients can be positive, negative, or zero, and they play a crucial role in determining the value of the expression when the variable is assigned a specific number.
What is the algebraic expression for 84 divided by the number z?
The algebraic expression for 84 divided by the number ( z ) is ( \frac{84}{z} ). This expression represents the quotient of 84 and the variable ( z ).
What the vaule of x?
x is a variable that represents an unknown number and its value depends on the algebraic expression it is used in.
What is the difference between a variable and a algebraic expression?
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.
In the expression 4a the number 4 is a(n)?
In the expression 4a, the number 4 is a coefficient. It represents the multiplicative factor applied to the variable ( a ), indicating how many times ( a ) is being scaled or multiplied. Coefficients can be any real number, and in this case, it is a constant that modifies the variable.

Is 4d a variable or is it a numerical exspression?
In the context of algebra, "4d" would typically be considered a numerical expression rather than a variable. A variable is typically a letter or symbol that represents an unknown quantity that can vary, while a numerical expression is a combination of numbers and mathematical operations. In this case, "4d" represents the product of the number 4 and the variable "d," making it a numerical expression.
What algebraic expression represents the phrase 100 less than a number?
Your variable (a number) X, minus 100. X - 100

What is the algebraic expression for 12 divided by a number?
The algebraic expression for 12 divided by a number is 12/x, where x represents the unknown number being divided into 12. This expression represents the quotient of 12 divided by the unknown number x. It can also be written as a fraction, 12 over x.
How do you write an expression for five times a number plus three?
If the variable x represents the number: 5x + 3ParenthesesExponentsMultiplyDivideAddSubtractAlways remember this
Which of the following verbal expression represents the algebraic expression 2x-8?
The verbal expression that represents the algebraic expression 2x-8 is "twice a number decreased by 8." In this expression, "2x" represents twice the value of a variable "x," and "-8" indicates that 8 is being subtracted from that value. Therefore, "twice a number decreased by 8" accurately describes the algebraic expression 2x-8.
What do you call replacing a variable in an expression by a number?
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
