Definition: If a = b, then ac = bc. This is called the ________ ________ of equality. (2 words)
Example: If x = 5, then 3x = (3)(5).
ANSWER: Multiplication property
To find the answer to this question, we can first focus on understanding the given example. The example states that if x equals 5, then 3x can be determined by multiplying 3 and 5. This illustrates the concept that if two quantities are equal (in this case x and 5), then when both quantities are multiplied by the same number (3 in this case), the results will also be equal.
Now, let's use this understanding to identify the term or principle described in the question. The given definition states that if a = b, then ac = bc. This means that if two quantities are equal (a and b), then when both quantities are multiplied by the same number (c), the results will also be equal.
Based on this information, we can conclude that the term or principle being described in the question is the Multiplication Property of Equality.
