An open sentence is a mathematical statement with variables that can be true or false depending on the values assigned to the variables. An expression, on the other hand, is a mathematical phrase that combines numbers, variables, and operations but does not contain an equal sign, so it does not represent a relationship or a statement. In simpler terms, an open sentence is like a question that can be answered, while an expression is like a calculation that can be simplified.

What is a replacement for the variable in an open sentence?
A replacement for the variable in an open sentence is called a "substitution." In mathematical terms, it refers to the process of replacing the variable with a specific value or expression to evaluate the truth of the statement. For example, in the open sentence "x + 2 = 5," substituting x with 3 would allow you to check if the equation is true or false.
What is a number called that when substituted into an open sentence it makes the sentence true?

How do you determine whether a given value is a solution to an open sentence in math?
To determine if a given value is a solution to an open sentence in math, substitute the value into the equation or inequality. Then, simplify the expression to see if it holds true. If the resulting statement is valid (e.g., a true equation or a satisfied inequality), the value is a solution; if not, it is not a solution.
Why an open sentence always has at least one variable?
An open sentence is neither true nor false. It depends on the value of the variable. If you had 5=3 that would be a closed sentence which is false. If you had 5=5 that would be a closed sentence which is true. If you had x=3 then it is open to whether the x is a 5 or a 3.

Can an open sentence must contian a viariable?
Yes, an open sentence must contain a variable, as it is an expression that can be true or false depending on the value of that variable. For example, in the open sentence "x + 2 = 5," the variable "x" represents an unknown value that can change the truth of the statement. Without a variable, the sentence would be a closed statement with a definitive truth value.
Is 3w-7 an open sentence?
Yes, the expression (3w - 7) is considered an open sentence because it contains a variable ((w)) and does not have a specific value assigned to it. Open sentences can take on different values depending on the value of the variable. In contrast, a closed sentence would have a specific value or statement, such as (3w - 7 = 0).
