Будет ли число 6 решением неравнества а) 15+х>40 б)2+у<96 в)54:t>1 г)48-n<39 д)а+a<20 e)0:b>5?

Answer 1

Число шесть получается под ,,б в"

Answer 2

Ответ получается под буквай А

Answer 3

a) 15х > 40

To determine if the number 6 is a solution to the inequality 15х > 40, we substitute x = 6 into the inequality and check if the resulting statement is true or false.

By substituting x = 6 into the inequality, we get:

15 * 6 > 40 90 > 40

The statement 90 > 40 is true, so 6 is indeed a solution to the inequality 15х > 40.

б) 2у < 96

To determine if the number 6 is a solution to the inequality 2у < 96, we substitute у = 6 into the inequality and check if the resulting statement is true or false.

By substituting у = 6 into the inequality, we get:

2 * 6 < 96 12 < 96

The statement 12 < 96 is true, so 6 is indeed a solution to the inequality 2у < 96.

в) 54 : t > 1

To determine if the number 6 is a solution to the inequality 54 : t > 1, we substitute t = 6 into the inequality and check if the resulting statement is true or false.

By substituting t = 6 into the inequality, we get:

54 : 6 > 1 9 > 1

The statement 9 > 1 is true, so 6 is indeed a solution to the inequality 54 : t > 1.

г) 48 - n < 39

To determine if the number 6 is a solution to the inequality 48 - n < 39, we substitute n = 6 into the inequality and check if the resulting statement is true or false.

By substituting n = 6 into the inequality, we get:

48 - 6 < 39 42 < 39

The statement 42 < 39 is false, so 6 is not a solution to the inequality 48 - n < 39.

д) а + а < 20

To determine if the number 6 is a solution to the inequality а + а < 20, we substitute а = 6 into the inequality and check if the resulting statement is true or false.

By substituting а = 6 into the inequality, we get:

6 + 6 < 20 12 < 20

The statement 12 < 20 is true, so 6 is indeed a solution to the inequality а + а < 20.

е) 0 : b > 5

To determine if the number 6 is a solution to the inequality 0 : b > 5, we substitute b = 6 into the inequality and check if the resulting statement is true or false.

By substituting b = 6 into the inequality, we get:

0 : 6 > 5 0 > 5

The statement 0 > 5 is false, so 6 is not a solution to the inequality 0 : b > 5.

In summary: - The number 6 is a solution to the inequalities 15х > 40, 2у < 96, and 54 : t > 1. - The number 6 is not a solution to the inequalities 48 - n < 39 and 0 : b > 5. - The number 6 is a solution to the inequality а + а < 20.
