4.9*0.75=
8.3x-4.9=5.2x+20.52

很高兴能够在这里回答你的问题,应该为:.3x-4.9=5.2x+20.523x-2x=20.52+4.9x=25.42再问:8.3x-4.9=5.2x+20.521.5(x+3.3)0.5=11.63

0.75-0.6+X=1.05

0.75-0.6+X=1.050.15+x=1.05x=1.05-0.15x=0.9

0.75=(  )16

根据题干分析可得:0.75=1216=75%=9:12=七五折.故答案为:12;75;9;七五.

0.75-3/16=多少

0.75-3/16=3/4-3/16=12/16-3/16=9/16

80除以0.75=?

用计算器捣嘛等于106.667

14.3÷()=0.75

14.3÷(286/15)=0.75

解方程: 4.9+0.5x=5.6 1-75%x=0.75 40.6=x:910

(1)4.9+0.5x=5.6,    4.9+0.5x-4.9=5.6-4.9,      &nb

15.25-3.1+0.75-4.9简便运算

15.25-3.1+0.75-4.9=(15.25+0.75)-(3.1+4.9)=16-8=8【秋风燕燕为您答题,肯定对】有什么不明白可以对该题继续追问请及时选为满意答案,

解方程 3.5x+1.4=4.9

3.5X十1.4=4.93.5X=4.9一1.4X=3·5÷3.5X=1再问:3x加2x减1.5x等于53.9再答:3X十2X一1.5X=53.93.5X=53.9X=53.9÷3.5X=

递等式能巧算的要巧算 0.49[1/(4.9-4.89)]+6 38.2*7.5+75+0.75*518

0.49[1/(4.9-4.89)]+6=0.49÷0.1+6=0.49+6=6.4938.2*7.5+75+0.75*518=0.75×(382+518)=0.75×900=675

0.75吨=( )千克

0.75吨=(750)千克

0.75-5x=0.75怎么算

0.75-5X=0.75-5X=0.75-0.75-5X=0X=0

(0.75*3.24+1.76*75%)/0.75 =0.75*(3.24+1.76)/0.75 =5

75%就是0.75再问:咋有3个0.75

5-0.25+0.75 = =

5-(0.25-0.75)再问:错再答:5+0.5再答:5.5再答:要变号再问:恩

x+6x=4.9解方程

7x=4.9x=0.7

4.9/()=0.75

4.9/(98/15)=0.754.9/0.75=4.9×4/3=98/15
