一道数学题,(-7)×(-5)-90÷(-15)
(-7)×(-5)-90÷(-15)
计算 第一个(-7)(+5)-90÷(-15) 第2个(-7)(+5)-90÷(-15)谢谢了,
计算:(要过程)(-7)×(-5)-90÷(-15)
(-7)x(-5)-90除(-15)求列式过程
(-7)x(-5)-90÷(-15)写出过程
90×(7/9+5/6-8/15)÷21/33 90×(7/9+5/6-8/15)÷21/33
90×(7/9+5/6-8/15)÷2又1/33
5*(-2)-90除以(-15)等于几
X*(1+15%)*90%-X=7
15:7分之5(化简)
7,15,25,),),
5X+2(15-X)=90解方程
找归率0,7,5,9,10,11,15(),()
