1.8x=0.972

0.273/X=0.35两边同乘以x0.273=0.35*X两边同除以0.35x=0.78Xx1.8=0.972两边同除以1.8x=0.54x/0.765=90 两边同乘以0.765x=68.85

5*3-x/2=8 x/2=7 x=140.273*x=0.35 x=0.35/0.273=1.281.8x=0.972 x=0.972/1.8=0.54

解:x*1.8=0.972 x=0.972/1.8 x=0.54

5*3-x/2=8 15-x/2=8x/2=7x=140.273/x=0.35 0.35x=0.273x=0.781.8x=0.972 x=0.54x/0.756=90x=68.04 9x-40=5 9x=45x=5x/5+9=21 x/5=12x=6048=27+5x5x=48-275x=21x=4.2

你好!1.8X(2-1.4)X0.9=2*0.9^2*0.6=0.81*1.2=0.81+0.162=0.972我的回答你还满意吗~~

小钢板体积=1.8/6=0.972立方米.

解:解方程, 此方程的解为x = 27/50,【即等于0.54】 1.8x = 0.972 x = 0.972 ÷ 1.8 x = 972/1000 ÷ (1*10+8)/10 x = 243/250 ÷ 18/10 x = 243/250 ÷ 9/5 x = 243/250 * 5/9 x = 27/50 ∴x = 0.54 答:此方程的解为x = 27/50,【即等于0.54】

0.273÷x=0.35 x=0.273÷0.35 x=0.78 1.8x=0.972 x=0.972÷1.8 x=0.54 x÷0.756=90 x=90*0.756 x=68.04

x/0.35-6.3=1.7x/0.35=8x=8*0.35=2.8

0.5+x)+x=9.8÷2 2(X+X+0.5)=9.8 25000+x=6x 3200=450+5X+X X-0.8X=6 12x-8x=4.8 7.5*2X=15 1.2x=81.6 x+5.6=9.4 52-x =15 91÷x =1.3 X+8.3=10.7 15x =3 3x-8=16 7(x-2)=2x+3 3x+9=2718(x-2)=270 12x=300-4x 7x+5.3=7.4 3x÷5=4.8 30÷x+25=85
