What number must you add to -6 to get a sum of zero? Explain

1 answer:

6 0

You would have to add a positive 6 to the negative 6 to get zero. Lets say you have -2 in order to get it to zero or just any positive number, you have to add a positive of the same value or higher to be able to get it there. I hope you understand that.

Answer:

$0.95*10^8$

Step-by-step explanation:

Hello!

Rules for scientific notation format:

Has to be multiplied to a power of 10
One factor has to be greater than 1 but less than 10

$\bold{0.95*10^8}$

There is a multiplication to a power of 10, but the other factor is less than 1.

This is NOT in Scientific Notation.

All the other options have a multiplication operation to a power of 10, and all the other factors are above 1 and less than 10.
