口算1.10-5.4= 2.4÷20= 3.5×200= 4.1.5-0.06= 5.0.75÷15= 6.0.4×0.8= 7.4×0.25= 8.0.36+1.54= 9.1.01×99= 10.420÷35= 11.25×12= 12.135÷0.5= 13.3/4 + 1/4 = 14.2 + 4/9 = 15.3 - 2/3 = 16.3/4 - 1/2= 17.1/6 + 1/2 -1/6 = 18.7....

[3/4-7/8/(5/6+4/5)]*28 =[3/4-7/8÷49/30]*28 =[3/4-15/28]*28 =3/4*28-15/28*28 =21-15 =6 (1.25*4/5-0.76)/(1又3/8+1又1/40) =(1-0.76)/2.4 =0.24/2.4 =0.1 [(0.2+1/3)*4.5]/(8又1/20-6.45) =8/15*4.5/1.6 =2.4/1.6 =1.5 x+3又2/3=5 x*9又3/...

800/5/8=20元 (35-20)*28=420元 答赚了420

解: 2x-2-3x<3 -x<5 x>-5 所以原不等式解集为x>-5 晕,图片传不上去……数轴会画吧?就像直尺上面一样,然后在-5位置处画个小圈(空心的),从小圈处向上延伸一小条线段,然后向右画
