Question

В двух танкерах одинаковое кол-во нефти. Если из одного танкера перелить в другой 29 т, то нефти в первом танкере останется в 2 раза меньше, чем станет во втором. Сколько всего нефти в обеих танкерах

Answer 1

х в одном танкере

(х-29)*2=х+29

2х-58=х+29

2х-х=29+58

х=87 в одном

87+87=174 тонны

Ответ. в двух танкерах 174 тонны нефти

 

Answer 2

Calculation of Oil in the Tankers

To calculate the total amount of oil in both tankers, we need to use the information provided in the question. Let's break down the given information:

- Initially, both tankers have the same amount of oil. - When 29 tons of oil is transferred from one tanker to the other, the amount of oil in the first tanker becomes twice as small as the amount in the second tanker.

Let's assume the initial amount of oil in each tanker is x tons. After transferring 29 tons of oil, the amount of oil in the first tanker becomes x - 29 tons, and the amount in the second tanker becomes 2(x - 29) tons.

According to the given information, the amount of oil in the first tanker is now 2 times smaller than the amount in the second tanker. Mathematically, we can express this as:

x - 29 = (2)(x - 29)

Now, let's solve this equation to find the value of x, which represents the initial amount of oil in each tanker.

x - 29 = 2x - 58

-x = -29

x = 29

Therefore, the initial amount of oil in each tanker is 29 tons.

To find the total amount of oil in both tankers, we can simply add the amounts together:

Total amount of oil = Amount in the first tanker + Amount in the second tanker

Total amount of oil = 29 + 2(29) = 29 + 58 = 87 tons

So, the total amount of oil in both tankers is 87 tons.
