Answer 2

Problem 509: Сумма двух последовательных чисел равна 463. Найдите эти числа.

To solve this problem, we need to find two consecutive numbers whose sum is equal to 463.

Let's assume the first number is x. Since the numbers are consecutive, the second number will be x + 1.

According to the problem, the sum of these two numbers is 463. So we can write the equation:

x + (x + 1) = 463

Simplifying the equation, we get:

2x + 1 = 463

Subtracting 1 from both sides, we have:

2x = 462

Dividing both sides by 2, we get:

x = 231

Therefore, the two consecutive numbers whose sum is 463 are 231 and 232.

Answer: The two numbers are 231 and 232.

Problem 511: Мама на 5 лет моложе папы, а сумма их возрастов равна 75 лет. Сколько лет маме и сколько лет папе?

To solve this problem, we need to find the ages of the mother and father given that the mother is 5 years younger than the father, and the sum of their ages is 75.

Let's assume the father's age is x. Since the mother is 5 years younger, her age will be x - 5.

According to the problem, the sum of their ages is 75. So we can write the equation:

x + (x - 5) = 75

Simplifying the equation, we get:

2x - 5 = 75

Adding 5 to both sides, we have:

2x = 80

Dividing both sides by 2, we get:

x = 40

Therefore, the father is 40 years old. To find the mother's age, we subtract 5 from the father's age:

40 - 5 = 35

Answer: The mother is 35 years old and the father is 40 years old.
