Vocabulary Review: Classify the equation(s) in which the variable is isolated.
The variable is isolated
Vocabulary Review: Match each equation on the left with its solution on the right.
Use Your Vocabulary: Identify and categorize each statement on the left based on whether or not it is a logical deduction.
A multiple of 5 always ends in 0 or 5. So, 240 is a multiple of 5.
If a number is a whole number, it is also a rational number. So, all rational numbers must be whole numbers.
Consider a + b = 100 for values of a and b. When a increases, b decreases. So, when b increases, a decreases.
