Ответ:

Для решения этой задачи нужно сначала найти общий множитель чисел 2, 7 и 5. Найдем его, поделив наибольший из них на остальные числа, пока не получим целое число:

7 / 2 = 3.5

5 / 2 = 2.5

7 / 5 = 1.4

Максимальный общий множитель равен 2. Теперь мы можем представить число 35 как сумму трех слагаемых, пропорциональных числам 2, 7 и 5:

35 = 2x + 7y + 5z

Для нахождения коэффициентов x, y и z можно воспользоваться методом подбора. Например, можно начать с x = 10 (так как 2 × 10 = 20, что близко к 35), а затем подбирать значения y и z так, чтобы сумма была равна 35:

2 × 10 + 7 × 2 + 5 × 2 = 35

Таким образом, число 35 можно представить в виде суммы трех слагаемых, пропорциональных числам 2, 7 и 5, следующим образом:

35 = 2 × 10 + 7 × 2 + 5 × 2.

Пошаговое объяснение:


oil9rvmwvxjz: 2×10+7×2+5×2= 20+14+10= 44. А должно быть равно 35. Похоже, ваш ответ неверный.

I just had to write today about the latest urban
development plans. Have you read them? They want
to knock down some 200-year-old houses and use the
land to build ... yes, you guessed! A housing estate with
100 modern homes. I know there's a shortage of housing
in our town, but it's not as if they're getting rid of

Luckily, it's not all bad news. At the moment, the river is

The shopping centre is a terrible idea. Now everyone

by the river instead, many places in the centre may end
up closing, which would be a disaster!
