Question

Продолжительность дня А часов. Чему равна продолжительность ночи? Составьте выражение. Найди его значение при А=8; 10; 12.

Answer 1

А+Б=24
А-известно
отсюда Б=24-А

соответственно:
Б=24-8=16
24-10=14
24-12=12

Answer 2

Duration of Day and Night

The duration of a day can be calculated using the formula: 2A + 10 hours, where A is the duration of the night in hours.

Calculation for A = 8

For A = 8, the duration of the day would be: 2(8) + 10 = 26 hours

Calculation for A = 10

For A = 10, the duration of the day would be: 2(10) + 10 = 30 hours

Calculation for A = 12

For A = 12, the duration of the day would be: 2(12) + 10 = 34 hours

These calculations are based on the provided formula and the given values of A.
