Question

При каких значениях переменной неравенство а *30 <90 будет истинным?

Answer 1

Ответ:

Пошаговое объяснение:

а должно быть меньше 3

Answer 2

To find the values of the variable "a" for which the inequality "a * 30 < 90" is true, you can follow these steps:

1. Divide both sides of the inequality by 30 to isolate the variable "a":

   a * 30 < 90 a < 90 / 30 a < 3

2. The inequality is now in the form "a < 3", which means "a" must be less than 3 to satisfy the original inequality.

So, the values of the variable "a" that make the inequality "a * 30 < 90" true are any real numbers less than 3. In interval notation, it can be written as: "a ∈ (-∞, 3)".
