Key Concept Example 1 Divide Integers with Different Signs Find 51 (3). 51 (3) = 17The integers have different signs. The quotient is negative. Answer: 17 Example 1 CYP A.156 B.13 C.13 D.156 Find 169 (13). Example 2 Divide Integers with Different Signs The integers have different signs. The quotient is negative. Find. Answer: 11 Example 2 CYP A.31 B.17 C.17 D.31 Key Concept 3 Example 3 Divide Integers with the Same Sign Find 12 (2). 12 (2) = 6The integers have the same sign. The quotient is positive. Answer: 6 Example 3 CYP A.40 B.4 C.4 D.40 Find 32 (8). Example 4 ALGEBRA Evaluate 18 x if x = 2. Divide Integers with the Same Sign 18 x = 18 2 Replace x with 2. = 9Divide. The quotient is positive. Answer: The solution is 9. Example 4 CYP A.60 B.9 C.9 D.48 Evaluate 54 x if x = 6. Example 5 FINANCIAL LITERACY An October newspaper headline read that the total value of stocks held by Japanese financial institutions dropped from $987 billion to $900 billion in 6 weeks. What was the average change in value per week? Y is the value of the stocks after 6 weeks, X is the initial value of the stocks. Answer: The average change in value was $14.5 billion per week. Divide. Example 5 CYP A.3F B.3F C.4F D.12F TEMPERATURE The temperature in Miami was 82F at 9:00 A.M. Four hours later the temperature was 94F. What was the average change in temperature per hour?
