What do you call replacing a variable in an expression by a number and simplifying the result?
That is called 'solving'.
What is to replace a variable with a number or anotherexpression in an expression?
The term for replacing a variable with another value or expression is "substitution."
What is an algebraic expression by replacing each variable with a given number and performing all operations?
It is called evaluating the equation.
What is a number that is multiplied by a variable in an expression?
The number is called the coefficient of the variable
What is a number sentence with a variable and an equal sign called?
a variable expression

What is replacing each variable with a number in an expression and simpiifying the result?
Evaluating the expression.
What is replacing each variable in an expression by a number and calculating the answer?
That is sometimes known as EVALUATING the expression.
What is an algebraic expression by replacing each variable with a given number and performing all operations?
It is called evaluating the equation.
Why replacing variable for a number in an expression or equation is called substituting?
Because you are substituting a number for a variable. Like substituting salt for sugar in a cake recipe. Although you really shouldn't do the latter.
What is a number that is multiplied by a variable in an expression?
The number is called the coefficient of the variable
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
What is a number sentence with a variable and an equal sign called?
a variable expression
What is the number that multiplies a variable?
The number that multiplies a variable in an algebraic expression is called a coefficient. It is the numerical factor that is multiplied by the variable to form a term in the expression.
The number that is multiplied by the variable in an algebraic expression?
It is called the coefficient of the variable
What is the number in front of a variable in a multiplication expression called?
The coefficient
