Question

Which of the following statements is not true about the numbers 7 and -7? They are opposite numbers. They form a zero pair. They have the same absolute value. They have a sum of -14.

Answer 1

We need to find which statement is not true:

Let us check each statement:

-They are opposite numbers.

Opposite numbers have the same distance away from zero. Hence, 7 and -7 are opposite numbers.

-They form a zero pair:

7-7 =0, the statement is true.

- They have the same absolute value

The absolute value is the not negative value no matter the sign.

Hence, l7l= 7 and l-7l= 7.

-They have a sum of -14.

Then:

7+(-7) = 0

Therefore, the last statement "They have a sum of -14" is not true.
