Mountain

The mountain has an elevation of 7450 meters and, in the morning, is the middle portion thereof in the clouds. How many meters of height is in the sky if the clouds are below 2,000 meters and the clouds above are two-fifths of the mountain's elevation?

Correct answer:

x =  2470 m

Step-by-step explanation:

$$\begin{gathered} h=7450\text{m} \\ a=2000\text{m} \\ b=\frac{2}{5}\cdot h=\frac{2}{5}\cdot 7450=\frac{2\cdot 7450}{5}=\frac{14900}{5}=2980\text{m} \\ x=h-b-a=7450-2980-2000=2470\text{m} \end{gathered}$$
