20.09×48-200.9×1.4+2009×0.66=20.09×48-20.09×14+20.09×66=20.09×(48-14+66)=20.09*100=2009
一、解方程.3X=X÷=125÷X=310=30%X=X-0.25=\x09X×=20×\x0950%X+X=3.625%X+15%X=X-15%X=68X-27X=X+X=121X+X=X+X=4X
100x+200=400100x=400-200x=200÷100x=250x+100=20050x=200-100x=100÷50x=210x+20=4010x=40-20x=20÷10x=2
因为3-2X>=0所以3>=2X所以X<=3/2又因为X>=M所以3/2>=X>=M所以M<=3/2所以,选B
