\(\frac{2x+1}{5}=\frac{y+3}{6}=\frac{2z-1}{7}\)

Áp dụng tính chất dãy tỉ số bằng nhau ta có: 

\(\frac{2x+1}{5}=\frac{y+3}{6}=\frac{2z-1}{7}=\frac{\left(2x+1\right)-\left(y+3\right)-\frac{1}{2}\left(2z-1\right)}{5-6-\frac{1}{2}.7}=\frac{-\frac{9}{2}}{-\frac{9}{2}}=1\)

\(\Leftrightarrow\hept{\begin{cases}2x+1=1.5=5\\y+3=1.6=6\\2z-1=1.7=7\end{cases}}\Leftrightarrow\hept{\begin{cases}x=2\\y=3\\z=4\end{cases}}\)

Gọi \(x\) là số học sinh giỏi lớp 5A. Theo đề bài ta có:

\(x\) x \(\dfrac{3}{5}\) = 6 ⇒ \(x\) = 6 x \(\dfrac{5}{3}\) = 10 (học sinh)

Vậy lớp 5A có 10 học sinh giỏi

Số học sinh lớp 5A là:

            6 : \(\dfrac{3}{5}\)\frac{3}{5}

= 10 ( em)

                     Đ/S: 10 em

\(20⋮x\Rightarrow x\inƯ\left(20\right)=\left\{1;2;4;5;10;20\right\}\)

Vậy \(x\in\left\{1;2;4;5;10;20\right\}\)

Lá xanh mỗi lần trôi xuống

Bỗng nhớ một vùng núi non.

Em hãy chỉ rõ những hình ảnh nhân hóa được tác giả sử dụng trong khổ thơ trên và nêu ý nghĩa của những hình ảnh đó.

Bài làm

Hình ảnh nhân hóa được tác giả bộc lộ trong khổ thơ. Điều đó được thể hiện rõ nét. Cửa sông dù giáp mặt với biển rộng nhưng chẳng dứt cội nguồn. Nghĩa là tác giả ca ngợi tấm lòng thủy chung, uống nước nhớ nguồn của con người. Đó là truyền thống vốn có của người dân Việt Nam.

29 tháng 4 2020

Qua những hình ảnh trên, tác giả muốn ca ngợi tình cảm (tấm lòng) luôn gắn bó, thuỷ chung, không quên cội nguồn (nơi đã sinh ra) của mỗi con người.

Nếu số chia là 5 thì số dư lớn nhất phải bé hơn số chia 1 đơn vị .

=> Ta có : 5 - 1 = 4 ( đơn vị )

Vậy số dư lớn nhất là 4 đơn vị .

18 tháng 2 2018

Vì số dư phải nhỏ hơn số chia. Mà số chia là 5 

=> Số dư lớn nhất là: 5 - 1 = 4

Gọi số bị chia là a. Ta có:

a : 5 = 1214 ( dư 4)

   Suy ra a = 1214 x 5 + 4 = 6074
