Question

( 15/10 x + 25 ) : 2/3 = 60

Giúp

Answer 1

\(\left(\dfrac{15}{10}x+25\right):\dfrac{2}{3}=60\)

\(\dfrac{15}{10}x+25=40\)

\(\dfrac{15}{10}x=15\)

\(\Rightarrow x=10\)

Vậy \(x=10\)

Answer 2

(\(\dfrac{15}{10}\)x + 25) : \(\dfrac{2}{3}\) = 60

(\(\dfrac{3}{2}\)x + 25) : \(\dfrac{2}{3}\) = 60

\(\dfrac{3}{2}\)x + 25 = 60 . \(\dfrac{2}{3}\)

\(\dfrac{3}{2}\)x + 25 = \(\dfrac{120}{3}\)

\(\dfrac{3}{2}\)x + 25 = 40

\(\dfrac{3}{2}\)x = 40 - 25

\(\dfrac{3}{2}\)x = 15

x = 15 : \(\dfrac{3}{2}\)

x = 15 . \(\dfrac{2}{3}\)

x = \(\dfrac{15.2}{3}\)

x = \(\dfrac{30}{3}\)

x = 10

Vậy x = 10
