What else can I help you with?
Is x-x a variable expression?
Yes. It is equal to zero. Yes, mathematical expressions can contain numbers, variables, and mathematical operations but do not contain an equal sign or inequality sign.
Does expression not contain an equal sign?
All expressions DO contain equals signs.
What is a statement that compares two expressions by using or any other inequality sign?
That is called an inequality.
How do you spell equal sign?
inequality sign
If you replace the equal sign of an equation an put an inequality sign in its place is there ever a time when the same value will be a solution to both the equation and inequality?
Yes, when the inequality has a less that or equal to sign, or a greater than sign or equal to sign, then the equal sign can be replaced and get a solution that is common to both the equation and the inequality. There can also be other solutions to the inequality, where as the solution for the equation will be a valid one.

Is 3x 114 an equation or an inequality?
3x = 114 is an equation because it states that two expressions are equal to each other, whereas an inequality would involve a greater than, less than, greater than or equal to, or less than or equal to sign.
What are the critical features of an inequality?
An inequality must have a greater than sign (>) OR a less than sign (<) OR a greater than or equal to sign (≥) OR a less than or equal to sign (≤).
When graphing a linear inequality the first step is to replace the inequality symbol with what sign?
With the equal sign (=).
What is inequality in algebric equation?
An inequality is similar to an equation, in that it compares two expressions. But in an equality, instead of an equal sign, you would usually use one out of the following inequality symbols:* less than * less than or equal * greater than * greater than or equal
What is the inequality sign for at least?
The sign is "greater than or equal to" or ≥
What represents expressions that are not equal?
An equal sign (=) with a slash through (/) represents that two expressions are disproportional.
Can expressions have and equal sign with a variable?
Expressions never have equality signs
