Wyrażenia algebraiczne kl. 6 ! C E L (-6a)-ab+13b-2b+18c-2c+1/4c= a= (-1/2) b=(-0,8) c=(-3/8)

(-6a)-ab+13b-2b+18c-2c+1/4c=-6a-ab+13b-2b+18c-2c+1/4c=-6a-ab+11b+16c+1/4c= -6*(-0,5)-(-0,5*(-0,8))+11*(-,08)+16*(-0,375)+1/4*(-0,375)=3-0,4-8,8-6+1/(-1,5)= 7,46666666

a= (-1/2) b=(-0,8) c=(-3/8) (-6a)-ab+13b-2b+18c-2c+1/4c= =(-6*(-1/2))-(-1/2)*(-0,8)+13*(-0,8)-2*(-0,8)+18*(-3/8)-2*(-3/8)+ +1/4*(-3/8)= 3-2/5+(-10i2/5)+1i3/5-6i3/4+3/4-3/32= =3-9i1/5-6-3/32= =-3-9,2-3/32= =-12,2-3/32= =12i64/320-30/320= =12i34/320= =12i17/160 NIE WIEM CZY DOBRZE!!!
