What is the sum of any number and it’s addictive inverse

the sum of any number and it’s addictive inverse is going to always be 0

Step-by-step explanation:

There aren’t really any steps to take...

For example, 1+-1 is 0

It would be zero.

Step-by-step explanation:

For example, the additive inverse of the positive number 5 is -5. That's because their sum, or 5 + (-5) = 0

what is all that apply?

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
