Answer 2

3)при значении a 6 )))))))

Answer 3

To find the value of "a" for which the expression 3a - 7 is greater than 11, we can set up an inequality and solve for "a".

The inequality representing the condition is: 3a - 7 > 11

Now, let's solve for "a" for each given option:

1. For a = 2: 3 * 2 - 7 = 6 - 7 = -1, which is not greater than 11. (False)

2. For a = 7: 3 * 7 - 7 = 21 - 7 = 14, which is greater than 11. (True)

3. For a = 6: 3 * 6 - 7 = 18 - 7 = 11, which is not greater than 11. (False)

4. For a = 5: 3 * 5 - 7 = 15 - 7 = 8, which is not greater than 11. (False)

So, the correct answer is option 2) a = 7. When "a" is 7, the expression 3a - 7 is greater than 11.
