(2.7X 3.1)*2-10(0.1X 0.08) 5.1(x-2)-3(1.2x-2)

Question

(2.7X 3.1)*2-10(0.1X 0.08)
5.1(x-2)-3(1.2x-2)

Answer 1

8,37*2 - 0,8 =15,94

 

5,1х -5,1*2 - 3*1,2х + 6 = 5,1х-3,6х - 4,2 = 1,5х - 4,2

Answer 2

 

(2.7X 3.1)*2-10(0.1X 0.08)=8,37*2-10*0,008=16,74-0,08= 16,66

5.1(x-2)-3(1.2x-2)= 5,1х-10,2-3,6х+6=1,5х-4,2
