Question

15 > 2x - 7> 7. where x ER​

Answer 1

Answer:

Solve 24x < 100, when (i) x is a natural number (ii) x is an integer

Answer:

The given inequality is 24x < 100

=> x < 100/24

=> x < 25/6

(i) It is evident that 1, 2, 3, and 4 are the only natural numbers less than 25/6

Thus, when x is a natural number, the solutions of the given inequality are 1, 2, 3, and 4.

Hence, in this case, the solution set is {1, 2, 3, 4}.

(ii) The integers less than are ...–3, –2, –1, 0, 1, 2, 3, 4.

Thus, when x is an integer, the solutions of the given inequality are ...–3, –2, –1, 0, 1, 2, 3, 4.

Hence, in this case, the solution set is {...,–3, –2, –1, 0, 1, 2, 3, 4}.
