答案
一、选择题：(共30分)
BCDDD,CBBCD
二、填空题：（共24分）
11.2<x<8 12. x≤6
13.三 14. 40
15. ①②③
三、解答题：（共46分）
16. 解:第一个不等式可化为
x－3x+6≥4，其解集为x≤1．
第二个不等式可化为
2(2x－1)＜5(x+1)，
有 4x－2＜5x+5，其解集为x＞－7．
∴ 原不等式组的解集为－7＜x≤1．
把解集表示在数轴上为：

17. 解：原方程可化为
∴
两方程相减，可得 37y+74=0，
∴ y=－2．从而 ．
因此，原方程组的解为
18. ∠B=∠C。 理由：
∵AD∥BC
∴∠1=∠B，∠2=∠C
∵∠1=∠2
∴∠B=∠C
19. ¬ 解:因为∠AFE=90°,
所以∠AEF=90°-∠A=90°-35°=55°.
所以∠CED=∠AEF=55°,
所以∠ACD=180°-∠CED-∠D
=180°-55°-42=83°.
20.（1） A′(2,3),B′(1,0),C′(5,1).
（2）如右图
（3）如图,过点B′作B′D⊥x轴，过点A′
作DE平行x轴，交B′D于点D，过点C′作
FE⊥x轴，交DE于点E，则B′D=3，DE=4，
FE=3
S△A′B′C′= SDB′C′E- S△DB′A′-S△EA′C′-S△B′C′F
= B′C′•DB′- DA′•DB′- A′E•EC′- B′F•C′F
=4×3- ×1×3- ×3×2- ×4×1
=12-1.5-3-2
=5.5
21分组 频数 百分比
3.5～5.5 3 6%
5.5～7.5 9 18%
7.5～9.5 18 36%
9.5～11.5 14 28%
11.5～13.5 6 12%
合计 50 100%
22. 解：设甲、乙两班分别有x、y人.
根据题意得
解得
答：甲班有55人,乙班有48人.
23.解：设每天安排x名工人生产螺栓，y名工人生产螺母。
解得
答：每天安排20名工人生产螺栓,100名工人生产螺母，恰好能是每天生产出来的产品配成一套。
24. 解：设用A型货厢x节，则用B型货厢（50-x）节，由题意，得
解得28≤x≤30．
因为x为整数，所以x只能取28，29，30．
相应地（5O-x）的值为22，21，20．
所以共有三种调运方案．
第一种调运方案：用 A型货厢 28节,B型货厢22节；
第二种调运方案：用A型货厢29节,B型货厢21节；
第三种调运方案：用A型货厢30节,用B型货厢20节
