Question

Which of these numbers are 11 units from 0 on the number line? A 0 B+11 C-11

Answer 1

It can be either B. 11 or C. -11

Answer 2

Answer:  The correct options are

(B) +11

(C) -11.

Step-by-step explanation:  We are given to select the numbers from the options that are 11 units from 0 on the number line.

We know that

the distance between a and b on the number line is given by

$D=b-a,$ where b is greater than a.

So, we have

the distance between 0 and 0 on the number line is

$D=0-0=0~\textup{units}.$

The distance between +11 and 0 is

$D=+11-0=11~\textup{units}.$

The distance between -11 and 0 is

$D=0-(-11)=11.$

Thus, the required numbers that are 11 units from 0 are +11 and -11.

Options (B) and (C) are CORRECT.
