Answer: x-4 ≥12
Step-by-step explanation:
Hi, to answer this question we have to know what an inequality and a variable are:
Inequality: An inequality is a expression that compares two values, showing if one is less than, greater than, or simply not equal to another value.
Variable: is a symbol for a number that is unknown: they usually are letters (x;y).
An inequality that contains at least one variable could be:
x-4 ≥12
Answer:
Open sentence.
Step-by-step explanation:
An inequality that contains at least one variable is called an open sentence; it can also be an equation. That is, when you substitute a number for the variable in an open sentence, the resulting statement is either true or false.
Example,
Equation x + 2 = 3
Until we know what the value of "x" is, we don't know if "x + 2 = 3" is true or false.
