Identify the property illustrated in each statement. Assume all variables represent real numbers. (7.5-y)+0=7.5-y

Key Concepts

Identity Property of Addition

The Identity Property of Addition states that when you add zero to any number, the result is the original number. In the expression (7.5 - y) + 0 = 7.5 - y, adding zero does not change the value of (7.5 - y), illustrating this property.

Real Numbers

Real numbers include all the numbers on the number line, encompassing rational numbers (like integers and fractions) and irrational numbers (like √2 and π). In the context of the question, it is important to recognize that the variables and constants involved are assumed to be real numbers, which ensures the validity of the operations performed.

Algebraic Expressions

Algebraic expressions are combinations of numbers, variables, and operations. The expression (7.5 - y) is an algebraic expression where 'y' is a variable. Understanding how to manipulate and simplify these expressions is crucial for identifying properties like the one illustrated in the statement.
