Question

Do number 12 and 13 please thank you!!

Answer 1

12. The statement ' x+3 = 9'  is true sometimes.

How is this explained?

Let x= 6,

6 + 3 = 9 (true)

Let x= 5 ,

5 + 3 = 8 (not true)

13. Option c. The statement 'multiplicative inverse of a number is less than the original number' is true for all numbers greater than 1.

How is this explained?

Let us consider some numbers,

a) 1

The multiplicative inverse of 1 = 1

Thus, multiplicative inverse of this number is not less than the original number.

b) 2 (greater than 1)

The multiplicative inverse of 2 = 1/2

multiplicative inverse of this number is less than the original number.

c) 8/7 (greater than 1)

The multiplicative inverse of 8/7 = 7/8

Here, multiplicative inverse of this number is less than the original number.
