The difference of two numbers is 4.If the difference of their reciprocals is 4/21, find the numbers
解析 They are 10 and 2. 【解析】【详解】句意:两个数的差是8。它们的和是12。这两个数字是什么?根据“The difference(差)of two numbers is 8. Their sum(和)is 12.”可知,两个数的差是8,和是12,所以这两个数是10和2。故填They are 10 and 2.反馈 收藏 ...
解析 12 和 8。解析:设这两个数分别为 x 和 y。根据题意可得 x + y = 20,x - y = 4。将两个式子相加,2x = 24,解得 x = 12。把 x = 12 代入 x + y = 20,可得 y = 8。涉及的英语表达有 sum(和),difference(差)。语法规则主要是简单的数学运算表达和并列结构。
