ĐKXĐ: n<>3

Để C là số nguyên thì \(n+5⋮n-3\)

=>\(n-3+8⋮n-3\)

=>\(8⋮n-3\)

=>\(n-3\in\left\{1;-1;2;-2;4;-4;8;-8\right\}\)

=>\(n\in\left\{4;2;5;1;7;-1;11;-5\right\}\)

\(60\%\cdot x+\dfrac{2}{3}x=-76\)

=>\(\dfrac{3}{5}x+\dfrac{2}{3}x=-76\)

=>\(x\left(\dfrac{3}{5}+\dfrac{2}{3}\right)=-76\)

=>\(x\cdot\dfrac{19}{15}=-76\)

=>\(x=-76:\dfrac{19}{15}=-76\cdot\dfrac{15}{19}=-60\)

Để B là số nguyên thì \(5⋮n-3\)

=>\(n-3\in\left\{1;-1;5;-5\right\}\)

=>\(n\in\left\{4;2;8;-2\right\}\)

Để B nguyên thì 5 ⋮ (n - 3)

⇒ n - 3 ∈ Ư(5) = {-5; -1; 1; 5}

⇒ n {-2; 2; 4; 8}

\(\dfrac{-5}{8}\cdot\dfrac{-12}{29}\cdot\dfrac{8}{-10}\cdot5,8\)

\(=-\dfrac{5}{8}\cdot\dfrac{8}{10}\cdot\dfrac{12}{29}\cdot\dfrac{29}{5}\)

\(=-\dfrac{5}{10}\cdot\dfrac{12}{5}=-\dfrac{12}{10}=-1,2\)

3:

a: Chiều rộng là \(60\cdot\dfrac{2}{5}=24\left(m\right)\)

Diện tích mảnh vườn là \(60\cdot24=1440\left(m^2\right)\)

b: Diện tích phần đất trồng hoa là:

\(120:\dfrac{3}{5}=120\cdot\dfrac{5}{3}=200\left(m^2\right)\)

lớp 6 mà ko biết làm bài này thì chịu. lo học đi ha bn

chiều rộng là:

60.\(\dfrac{2}{3}\)=40(m)

a) DT mảnh vườn là:

60.40=2400(\(^{m^2}\))

b) DT phần đất trồng hoa là:

120:\(\dfrac{3}{5}\)=200(\(m^2\))
