\(\dfrac{3}{x+3}=\dfrac{15}{55}\\ \dfrac{3}{x+3}=\dfrac{3}{11}\)
`<=>(x+3)xx3=3xx11`
`(x+3)xx3=33`
`x+3=11`
`x=8`
Vậy `x=8`
`@An`
Chiều dài : `2/5xx2=4/5(km)`
Chu vi : `(2/5+4/5)xx2=12/5(km)`
DT : `2/5xx4/5=8/25(km^2)`
\(B=\dfrac{4}{9}\times\dfrac{1}{3}+\dfrac{4}{9}\times\dfrac{2}{3}+\dfrac{14}{9}\\ B=\dfrac{4}{9}\times\left(\dfrac{1}{3}+\dfrac{2}{3}\right)+\dfrac{14}{9}\\ B=\dfrac{4}{9}\times1+\dfrac{14}{9}\\ B=\dfrac{4}{9}+\dfrac{14}{9}\\ B=\dfrac{18}{9}=2\)
`CD=36:3/8=96(m)`
`DT=36xx96=3456(m^2)`
\(x-\dfrac{4}{3}=\dfrac{5}{4}.\left(\dfrac{1}{5}-4\right)\\ x-\dfrac{4}{3}=\dfrac{5}{4}.\left(\dfrac{-19}{5}\right)\\ x-\dfrac{4}{3}=\dfrac{-19}{4}\\ x=\dfrac{-19}{4}+\dfrac{4}{3}\\ x=\dfrac{-41}{12}\)
Vậy \(x=\dfrac{-41}{12}\)
Tổng vận tốc 2 xe ô tô : `210:2=105` ( km/h )
Tổng số phần bằng nhau : `2+3=5(phần)`
Vân tốc ô tô đi từ `A` : `105:5xx2=42` ( km/h )
Vận tốc ô tô đi từ `B` : `105:5xx3=63` ( km/h )
