F.2 Linear Equations
Ann had a bag of glass beads. She used half of the beads to make a necklace.She and her sister then 1/6 and 1/7 of the beads respectively to make two bracelets. If there are 16 glass beads, find the original number of glass beads. 詳細列式+分析呀 THX
最佳解答:
Let x be the original number of glass beads, x - (1/2) x - (1/6) x - (1/7) x = 16 (1 - 1/2 - 1/6 - 1/7) x = 16 (42/42 - 21/42 - 7/42 - 6/42) x = 16 (8/42) x = 16 x = 84 The original number of glass beads is 84
