Question

За год до рождения Карины её родителям вместе было 46 лет. Сколько сейчас лет Карине, если через 2 года ей и её родителям вместе будет 87 лет? ​СРОЧНООО!!!! ПОЖАЛУЙСТА!!!!

Answer 1

Ответ:

11 лет Карине сейчас

Пошаговое объяснение:

87 - 2*3 = 87 - 6 = 81 год Карине и её родителям сейчас

46 + 2 = 48 лет стало родителям через 1 год, когда родилась Карина

(81 - 48) : 3 = 33 : 3 = 11 лет Карине сейчас

Answer 2

Solution:

To solve this problem, we can use algebraic equations to represent the given information and then solve for Karina's current age.

Let's denote Karina's current age as K, her parents' combined age a year before her birth as P, and the total age they will have in two years as T.

We are given that a year before Karina's birth, her parents' combined age was 46 years. This can be represented as: P - 1 = 46.

We are also given that in two years, Karina's age plus her parents' combined age will be 87 years. This can be represented as: K + 2 + P + 2 = 87.

Now, we can solve these equations to find Karina's current age.

Calculation:

From the first equation, we can solve for P: P = 46 + 1 = 47.

Substitute P into the second equation: K + 2 + 47 + 2 = 87, K + 49 = 87, K = 87 - 49, K = 38.

Answer:

Karina is currently 38 years old.
