4567:567=8(dư 5 )

567:56=10(dư 1)

Mk chưa chắc đúng đâu, k cho mk nhá!

\(\Rightarrow x\left(2y+1\right)-3\left(2y+1\right)=7\)

\(\Leftrightarrow\left(x-3\right)\left(2y+1\right)=7=1.7=7.1=-1.-7=-7.-1\)

vậy....

cảm ơn bạn Nguyễn Xuân Anh rất nhiều

mình không biết

54.(40-7)-40.(54-7)

=54.33-40.47

=1782-1880

=-98

54.(40-7)-40.(54-7)=

= 54.33 - 40.47 

= 1782 - 1880

= -98 

\(B=\sqrt{371^2}+2\sqrt{31^2}-\sqrt{121^2}=371+2.31-121=371+62-121=312\)

người đó đến lúc : 11 giờ nha

đến b lúc:

7h45p+2h50p-25=10h10p

SAI THÌ MK SR NHA^^

Số vải đó dài:

       36:45x100=80(m)

             Đáp số:80 m vải

tấm vải đó dài: 36:45.100=80%

bạn lướt qua thấy đúng thì k nha cảm ơn bn nhìu

45x-38x=1505

=>7x=1505

=>x=215

X*(45-38)=1505

X*7=1505

X=1505:7

X=215
