Question

20,11 x 194 + 20,11 x 805 + 20,11

X x 3,4 + X x 1,2 = 23

Answer 1

20.11x194+20.11x805+20.11

=20.11x(194+805+1)

=20.11x1000=20110

X x 3.4 +X x1.2=23

X x( 3.4+1.2)=23

X x 4.6=23

X=23 :4.6=5

Answer 2

* \(20,11.194+20,11.805+20,11\)

\(=20,11.\left(194+805+1\right)\)

\(=20,11.1000\)

\(=20110\)

* \(x.3,4+x.1,2=23\)

\(\Leftrightarrow x.\left(3,4+1,2\right)=23\)

\(\Leftrightarrow x.4,6=23\)

\(\Leftrightarrow x=23:4,6\)

\(\Leftrightarrow x=5\)

(Nhớ k cho mình với nha!)

Answer 3

=20.11(194+805+1)=20.11*1000=20110

X(3.4+1.2)=23

X*23/5=23

X=5

Answer 4

1)20,11x194+20,11x805+20,11

=20,11x(194+805+1)

=20,11x1000

=20110

2) x.3,4+x.1,2=23

   x.(3,4+1,2)=23

           x.4,6=23

           x     =23:4,6

           x     =5

\(\Rightarrow\)x=5

Chúc bạn học tốt! nhớ k cho mình nhé ^^
