三、解答题(本题共42分,每题6分)

18. 解：(1)原式= -------------------3分

=-12+16-6

=-2 ---------------------6分

(2)原式=-1- ×(2-9)------------------3分

=-1- ×(-7)

= --------------------6分

19.解：(1)去括号得， 5x+40=12x﹣42+5 ----------------2分

移项合并同类项得，7x=﹣77 -------------4分

系数化为1得，x=11 ---------------6分

(2)去分母得，3(x+2)﹣2(2x﹣3)=12 -------------2分

去括号得， 3x+6﹣4x+6=12 ---------------4分

移项合并同类项得， ﹣x=0

系数化为1得， x=0 --------------6分

20.解：原式= --------------3分

当a=- 时，原式=

=- ----------------6分

21.解：设这个角的度数为x°，

由题意得： ----------------------4分

解得：x=80 ----------------------5分

答：这个角的度数是80°-----------------------6分

22.解：(1)依题意得，装饰物的面积正好等于一个半径为 的圆的面积，

即 = ;----------------3分

(2)依题意可知，能射进阳光的部分的面积=窗户面积-装饰物面积，

所以能射进阳光的部分的面积= ----------------------6分

四、综合题

23.(8分)解：(1)设运输路程是x千米，根据题意得

400+4x=820+2x ------------------3分

解得x=210 ------------------5分

答：若两种运输的总费用相等，则运输路程是210千米;

(2)若运输路程是800千米，

选择方式一运输的总费用是：400+4×800=3600(元)

选择方式二运输的总费用是：820+2×800=2420(元)

2420<3600，

所以若运输路程是800千米，这家公司应选用方式二的运输方式.-------------8分

24.(9分)解：(1)∠ACE=∠BCD，理由如下：

∵∠ACD=∠BCE=90°，∠ACE+∠ECD=∠BCD+∠ECD=90°，

∴∠ACE=∠BCD;---------------2分

(2)若∠DCE=30°，∠ACD=90°，

∴∠ACE=∠ACD﹣∠DCE=90°﹣30°=60°，

∵∠BCE=90°且∠ACB=∠ACE+∠BCE，

∴∠ACB=90°+60°=150°;-------------------5分

(3)猜想∠ACB+∠DCE=180°-------------------6分

理由如下：

∵∠ACD=90°=∠ECB，∠ACD+∠ECB+∠ACB+∠DCE=360°，

∴∠ECD+∠ACB=360°﹣(∠ACD+∠ECB)=360°﹣180°=180°;----------------8分

(4)成立.------------------------9分

25.(10分)(1)解：设x小时后两车相遇，

根据题意得：60x+80x=448，-------------------3分

解得 x=3.2

答：两车同时开出，相向而行，出发后3.2小时相遇。 -------------5分

(2)解：设快车开出y小时后两车相遇，

根据题意得：60( +y)+80y=448 -----------------8分

解得y=3

答：快车开出后3小时两车相遇。--------------------10分
