Concept 3: Translating to an Absolute Value Expression For Exercises 51–54, write an absolute value inequality equivalent to the expression given. (See Example 7.) 51. All real numbers whose distance from 0 is greater than 7 52. All real numbers whose distance from 3 is less than 4 53. All real numbers whose distance from 2 is at most 13 54. All real numbers whose distance from 0 is at least 6 55. A 32-oz jug of orange juice may not contain exactly 32 oz of juice. The possibility of measurement error exists when the jug is filled in the factory. If the maximum measurement error is 0.05 oz, write an absolute value inequality representing the range of volumes, x, in which the orange juice jug may be filled. (See Example 8.) 56. The length of a board is measured to be 32.3 in. The maximum measurement 0.2 error is in. Write an absolute value inequality that represents the range for the length of the board, x. 634 57. A bag of potato chips states that its weight is oz. The maximum ; 18 measurement error is . Write an absolute value inequality that represents the range for the weight, x, of the bag of chips. 1 78 oz 58. A -in. bolt varies in length by at most in. Write an absolute value 16 inequality that represents the range for the length, x, of the bolt. 59. The width, w, of a bolt is supposed to be 2 cm but may have a 0.01-cm margin of error. Solve 0w 2 0 and interpret the solution to the inequality in the context of this problem. 0.01,
