To evaluate an algebraic expression, replace the variable, the letters with their numerical values, true or false

True. To evaluate an algebraic expression, the variable(s) in the expression are replaced with their numerical values and then the expression is simplified using mathematical operations.

True. To evaluate an algebraic expression, you replace the variables (or letters) in the expression with their respective numerical values and then perform the necessary operations to simplify the expression.

True. To evaluate an algebraic expression, you replace the variables (letters) with their numerical values. By substituting the given values, you can perform the arithmetic operations to simplify the expression and obtain a numerical result. For example, if you have the expression 3x + 5 and the value of x is 2, you would replace the x with 2 and evaluate it as 3(2) + 5, which equals 11.
