n stands for a whole number, 2n is greater than 30,5n is less than 100 what are all the numbers that n stands for

Sagot :

16, 17, 18, 19, 20

If the n was equal to or greater than 30 you would have 15 as well but because the problem just says greater than don't include it.

Answer:

{16, 17, 18, 19} are the numbers.

Step-by-step explanation:

If n stands for a whole number and 2n is greater than 30.

Means 2n > 30

⇒ n > 15

Now another statement says 5n is less than 100

Means 5n < 100

⇒ n < 20

So n defines the values

20 > n > 15

If n is a whole number then numbers between 15 and 20 will be

{16, 17, 18, 19}. This set will not include 15 and 20 since n is not equal to these numbers.
