5-0.25+0.75==5-0.25+0.75==5-0.25+0.75==5-(0.25-0.75)
5-0.25+0.75 = =
5-0.25+0.75 = =
5-0.25+0.75 = =
5-(0.25-0.75)
5-0.25+0.75 = =
8/9*[0.75-(5/16+0.25)]=
×+1分之0.75=0.25
(-0.75)除以0.25=?
多元线性回归分析x1=[2 2 2 2 2 2 5 5 5 5 5 5 7 7 7 7 7 7 10 10 10 10 10 10];x2=[0 0 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1 0 0 0 1 1 1];x3=[0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25 0.50 0.75 0.25
计算 0.25*(-2.15)+0.75*(+3.15)/3=?
0.64*0.25+0.75= 的简便方法
1-0.75x=0.25 解方程
5.4-0.25=0.75的简便,
解方程:5/6-x=1/2 x+0.75-3/5=0.25
x-0.25-0.75=y+0.25解方程
-2^3*-(-1)^5*(-2)^4=?0.25*(-2.15)+0.75*(+3.15)/3=?一定要对
计算:(+3)+(+4)= (-2)+(+8)= (-0.25)+(+0.75)= (-2)+(-5)= (-9)+(+6)= 0+(-3.6)=
0.75+5/12=?
判断题:因为0.25+0.75=1,所以0.25和0.75互为倒数()
0.75-5x=0.75怎么算
0.75*4+0.75*5+3/4=
-6/11-7/9+4/9-5/11=?--0.25的绝对值+3/4-(-0.125)+-0.75的绝对值=?
