Question

Помогите пожалуста! Відомо що 10<а<15 Оцінити значення вираження 2а-3 Відповідь ?<2а-3<?

Answer 1

$10$

Все части неравенства умножаем на 2:

$2\cdot10$

$20$

От всех частей неравенства отнимаем 3:

$20-3$

$\boxed{17$

Answer 2

To evaluate the expression 2a - 3, where 10 < a < 15, we can substitute different values of a within the given range and calculate the corresponding values of the expression.

Let's start by substituting the lower limit of the range, a = 10: 2(10) - 3 = 20 - 3 = 17

Next, let's substitute the upper limit of the range, a = 15: 2(15) - 3 = 30 - 3 = 27

Therefore, the values of the expression 2a - 3, where 10 < a < 15, are between 17 and 27. In other words, 17 < 2a - 3 < 27.

I hope this helps! Let me know if you have any further questions.
