我翻譯一下吧,你看了應(yīng)該就會(huì)做了.
1、如果3,8和w的算術(shù)平均值大于或等于7,而且小于或等于44,那么w的最大可能值是多少?
44*3 - 3 - 8 = 121
2、一個(gè)矩形的玻璃板是否能夠完全覆蓋一個(gè)矩形的桌面,而且玻璃板的邊和桌面的邊是平行的?
(1)桌面36英寸寬,60英寸長(zhǎng).
(2)玻璃板面積是2400平方英寸.
選E,兩個(gè)條件相加也不充分.比如玻璃板是20*120.
3、n是一個(gè)兩位的正整數(shù),如果組成n的這兩個(gè)數(shù)字（比如n是14,則這兩個(gè)數(shù)字是1和4）的乘積是2,n是多少?
(1) n 是奇數(shù)
(2) n 比20大.
選D,兩個(gè)都單獨(dú)充分.因?yàn)槌朔e是2,所以n不是12就是21.(1)單獨(dú)即可保證n只能是21,(2)單獨(dú)即可保證n是21.
4、有n個(gè)學(xué)生,m個(gè)教室.如果 3
