The Additive inverse only works when you add a to its oppositie leaving a sum of 0
For example, says 5 represents a.
5 + b = 0
B, is 5's additive inverse: -5
The reciprocal of 9/10, however, is 10/9
6x-8=13 start off with adding 8 to 13 then 6x=21 then divide 6 to both sides getting x=3.5
To the nearest whole: 4
to the nearest hundredth: 4.2
actual answer: 4.5
