Stephanie set her rental car trip meter at 0, record for the women's shot put was while the odometer read 4962.8. She drove 22.41 meters, which was 5.09 meters less the same route round-trip from the airport than double the 1948 Olympic winning to her hotel. When Stephanie returned the distance. What was the women's winning car, the odometer read 5554 miles. What was shot put distance in the 1948 Olympics? the car trip meter reading after her trip from the airport to the hotel? 24. Astronomy The average density of Earth is 25. Zoology The Wilson's Storm Petrel has 5.5 g/cm', which is 0.1 g/cm less than 8 times a wingspan of 0.41 meter, which is 0.15 that of Saturn. What is the average density meter less than one fourth the wingspan of of Saturn? the Black-browed Albatross. What is the wingspan of the Black-browed Albatross? CHALLENGE Does the given value make the equation true? If false, tell what value makes he equation true. 6. 9 = (3m + 7m + 8) + 2, when m = 2.8 27. -1 2 2h +11 -3h, when h = 1.4 Chapter 4
