анонимВ универмаге за день продали на 14 детских пальто (52 пальто - 38 костюмов = 14 пальто) больше и так как их цена была одинаковой, то х руб было получено за счет продажи только этих 14 пальто. То есть, х/14 руб - цена одного детского пальто, а, соответственно, цена одного костюма такая же - х/14 руб.
Таким образом, за продажу 52 детских пальто в универмаге за один день было выручено 52 * х/14 = 26х/7 = 3 5х/7 руб. За проданные 38 костюма в тот же день было получено 38 * х/14 = 19х/7 = 2 5х/7 руб.

Space is amazing. The sheer vastness of it, along with the trillions upon trillions of objects in the many billion galaxies of the universe is almost incomprehensible to the human brain.
1.Space is completely silent.
There is no atmosphere in space, which means that sound has no medium or way to travel to be heard. Astronauts use radios to stay in communication while in space, since radio waves can still be sent and received.
2.The hottest planet in our solar system is 450° C.
Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C. Interestingly, Venus is not the closest planet to the Sun – Mercury is closer but because Mercury has no atmosphere to regulate temperature it has a very large temperature fluctuation.
3.There may be life on Mars.
Of all the planets in our solar system (apart from Earth), Mars is the one most likely to be hospitable to life. In 1986, NASA found what they thought may be fossils of microscopic living things in a rock recovered from Mars.
4.Nobody knows how many stars are in space.
The sheer size of space makes it impossible to accurately predict just how many stars we have. Right now, scientists and astronomers use the number of stars only within our galaxy, The Milky Way, to estimate. That number is between 200-400 billion stars and there are estimated to be billions of galaxies so the stars in space really are completely uncountable.
