计算:(1)-3y+0.75y-0.25y;(2)5a-1.5a+2.4a |
答案
(1)-3y+0.75y-0.25y =(-3+0.75-0.25)y =-2.5y.
(2)5a-1.5a+2.4a =(5-1.5+2.4)a =5.9a. |
举一反三
(______)-(-5x)=4x2-3x+2;2a2-5ab+4b2-(______)=a2-3ab. |
1-2a+a2=-(______)=1+(______). |
去括号7x3-[3x2-(x+1)]=______. |
已知15x2y与-xmyn与是同类项,则|-2m+n|+|m-3n|的值是______. |
下列各式中是同类项的是( )A.3x2y与3xy2 | B.-ab与abc | C.3x2与-3y2 | D.-a2b3c与0.5a2b3c |
