Do algebraic expressions have to have a variable?
Yes. That is the definition of an algebraic expression.
What is the definition of equivalent numerical expressions?
That means that the two expressions represent the same number.
How are equivalent expressions used?
You can use them to find a variable. Lets say you have two equivalent expressions with the same variable... x + 2x - 42 = 0 2x - 28 = 0 If you combine these equivalent expressions you ahve... x + 2x - 42 = 2x - 28 In all of the expressions you have x = 7 There are also other applications but its confusing to explain.
Two algebraic expressions are if they have the same value for all values of their variable?
They are identical or equivalent.
What is the definition for defining the variable?
choosing a variable to represent one of the unspecified numbers in a problem and using it to write expressions for the other unspecified numbers in the problem.
What is the definition of equivalen variable expressions?
Two expressions are "equivalent" if they have the same result for any values of the variable or variables.
Do algebraic expressions have to have a variable?
Yes. That is the definition of an algebraic expression.
What is the definition of equivalent numerical expressions?
That means that the two expressions represent the same number.
What is a statement that two numberical or variable expressions are equal?
equivalent equations

They are identical or equivalent.
What is Definition of equivalent?
two expressions that have the same value for all allowable replacements are called equivalent.
What is the definition for defining the variable?
choosing a variable to represent one of the unspecified numbers in a problem and using it to write expressions for the other unspecified numbers in the problem.
Can expressions have and equal sign with a variable?
Expressions never have equality signs
Which expression is equivalent to 4.8 2.2w-1.4w 2.4?
Lots of expressions are equivalent to it. But for a start, you may want to simplify it, by combining like terms - i.e., add the terms with the variable "w", and separately add the terms without a variable.
What does equivalent expressions in math mean?
It means that two expressions represent the same number; for example, 5 is equivalent to 3 + 2. If there are variables in the expression, it means that the two expressions will evaluate to the same number, for any value assigned to the variable or variables. For example, for any value of x, 2x is the same as x + x; therefore, the two are equivalent.
What Algebraic expressions?
An expression with a variable.
