???????
56,8 x 76,9 - 56,8 x 76,8
= 56,8 x (76,9 - 76,8)
= 56,8 x 0,1
= 5,68
\(3,7\times3,8+6,2\times3,7\\ =3,7\times\left(3,8+6,2\right)\\ =3,7\times10\\ =37\\ 56,8\times76,9-56,8\times76,8\\ =56,8\times\left(76,9-76,8\right)\\ =56,8\times0,1\\ =5,68\)
a) 56,8 x 76,9 - 56,8 x 76,8
= 56,8 x ( 76,9 - 76,8 )
= 56,8 x 0,1
= 5,68
b) 20,15 x 6,8 + 20,15 x 3,2
= 20,15 x ( 6,8 + 3,2 )
= 20,15 x 10
= 201,5

k mk nha thank you
\(4,6\times y+y+4,4\times y=2017\)
\(y\text{}\times\text{}\left(4,6+1+4,4\right)=2017\)
\(y\text{ }\times10=2017\)
\(y\text{ }=2017:10=201,7\)
x + 4,6 = 56,8
⇔ x =56,8-4,6
⇔ x=52,2
Vaayj x = 52,2
giúp mình với ạ
