Ede4ka [16]

Answer:

The weight of meteorite found in United States is 15.4 tons

Step-by-step explanation:

Given as :

A meteorite found in the United States weighs 7/10 as much as one found in Mongolia .

The weight of meteorite found in Mongolia = x = 22 tons

Let The weight of meteorite found in United States = y

∵The weight of meteorite found in United States = \dfrac{7}{10} × weight of meteorite found in Mongolia

i.e y =  \dfrac{7}{10} × x

Or, y =  \dfrac{7}{10} × 22 tons

Or, y = \frac{7\times 22}{10}

Or, y = \frac{7\times 11}{5}

∴  y = \dfrac{77}{5}

i.e y = 15.4 tons

So, The weight of meteorite found in United States = y = 15.4 tons

Hence, The weight of meteorite found in United States is 15.4 tons Answer
