Name ___________________________ Date _____________ Period _______ Integers, Opposites & Absolute Value III Order the integers from least to greatest. 1. |–7|, 2.5, |–1.5|, 0, –2.66 2. -|-9|, –4.34, -|12|, -(–11), (–1) 3. 0, -(–99), -|44|, –60.5, -16 In the Real World Geography The Global Positioning System (GPS) can be used to determine elevations. The table shows the minimum elevations of several countries. Which country in the table has the lowest elevation? Simplify, then write the opposite and the absolute value of the integer. 4. (–16) 5. –(-(140)) 6. –(|-1|) 7. (-|–55|) Use a number line to order the integers from least to greatest. 2. 5 2 6 , –10.65, 15.33, 27 , –20.5, 13.0 5 13 3. 120 2 5 , 62 , 0.5, –56.13, 74.75, –130 3 6 Simplify, then write the opposite and the absolute value of the integer. 4. (-(-(-|19|))) 5. (-|–8|) 6. |-(-(–740))| 7. –(|1327|) 8. Find the Error A student was asked to order the integers 3, 1, 0, –9, –2, and 5 from least to greatest. Describe and correct the error in the solution. Complete the statement with < or >. 9. 44.5 _ –6.23 10. –12.6 _ 1.12 11. –9 _ –2 12. 0 _ –5 13. 5 _ –5 14. –17 _ 2 15. 34 _ –29 16. –20 _ –14 Simplify, then order the integers from least to greatest. 17. -|64|, (–12), |18|, (59), (-|–20|), 44 18. -|278|, -(121), -(|–301|), 262, –155 Match the integer expression with the verbal expression. 19. – |7| 20. |– 7| 21. – |– 7| 22. – (– 7) A. the opposite of negative seven B. the opposite of the absolute value of seven C. the absolute value of D. the opposite of the absolute negative seven value of negative seven In Exercises 23 and 24, use the table showing elevations of lakes. 23. Compare Which lake is at a lower elevation, Gieselmann Lake or Silver Lake? 24. Arrange the lake elevations in order from least to greatest. Simplify the expression. 25. |–32| 26. –|9| 27. –|29| 28. –(–5) 29. –(–81) 30. – |–17| 31. – |–3| 32. –(–(–4)) Complete the statement with <, >, or =. 33. |4| _ |–4| 34. |–6| _ –|6| 35. – |–9| _ –(–9) 36. Critical Thinking What numbers have opposites that are the same as their absolute values? What numbers have opposites that are different from their absolute values? 37. Launch Countdown Put the following activities for a shuttle launch in the order that they occur. “T– 5 minutes” means 5 minutes before liftoff. Challenge Order the numbers from least to greatest. 38. –28, –(–73), |–65|, |95|, –|47| 39. |–19|, –74, –|12|, –(–56), –|–58|
