9.25×9.9+92.5% 36÷[(5/6%1/3)×3] X%2/5X=14

方程两边同时×6 3(3x+5)=2(5x-9) 9x+15=10x-18 -x=-33 x=33 望采纳

=29/3÷5/3+5.46÷13/5*(4.875-2.875)=29/5+2.1*2=5.8+4.2=10

2/9+1/4÷2/5+3/8 =2/9+1/4×5/2+3/8 =2/9+5/8+3/8 =2/9+(5/8+3/8) =2/9+1 =1·2/9 =11/9 2/3+(4/7-1/2)×1/12 =2/3+(4/7-1/2)×1/12 =2/3+4/7×1/12-1/2×1/12 =2/3+1/21-1/24 =14/21+1/21-1/24 =15/21-1/24 =5/7-1/24 =120/168-7/168 =113/168 2/3+...

如图

4▽5=4+5+6+7+8=30 x▽3=12 则x+(x+1)+(x+2)=12 所以 x=3

8.2x=32.8 x=32.8/8.2 x=____

1)x=105÷1.05=100 2)x=(59-9)÷0.25=240 3)x=(2.4+0.3)÷4/5=3.375 4)x=(0.8-0.75)÷2/3=0.075

=1/2×(1-1/3+1/3-1/5+1/5-1/7+17-1/9+1/9-1/11) =1/2×(1-1/11) =1/2×10/11 =5/11

1.x=20,2.x=33,如需过程,欢迎追问
