0.74÷0.8÷0.37 解:最优化的方法 =0.74÷0.37÷0.8 =2÷0.8 =2.5 祝学习进步。

24.8×6.3-6.3×16.5 83x0.37 =6.3*(24.8-16.5)+83*0.37 =6.3*8.3+8.3*3.7 =8.3*(6.3+3.7) =8.3*10 =83

24.8x6.3-6.3x16.5+ 83x0.37 =6.3x(24.8-16.5)+ 83x0.37 =6.3x8.3+ 83x0.37 =83x(0.63+0.37) =83x1 =83

3.7x12.8+0.37x872 =3.7x12.8+3.7x87.2 =3.7x(12.8+87.2) =3.7x100 =370

24.8x6.3-6.3x16.5+83x0.37 =6.3*(24.8-16.5)+83x0.37 =6.3*8.3+83*0.37 =8.3*(6.3+3.7) =83 满意采纳奥

三边比3:4:5,最小的那个角37度

指导意见: 这个一般就是有下结忆肝病毒就是用一些干扰素,就要以达到治疗的效果就会好的,.

X+0·8=37.2/12=3.1 X=3.1-0.8=2.3

7.8×0.37 +0.78×6.3巧算 =7.8×(0.37+0.63) =7.8×1 =7.8
