The distance between A and B is d = |B - A|
We have d = 3 and A = 12.
Substitute:

<h3>Answer: 9 and 15.</h3>
Answer:
you round off to the nearest hundred which is 672 and 830 which I find to to 672 and 830 becomes 1000
5.5 in fraction is 5 1/2
hope that helps :)
D=60. multiply both sides of the equation by 4 since it’s a factor, giving you 2d-20-d=40. since there are like terms with d, collect them to get d-20=40 and move 20 to the right and change it’s sign. that will give you d=40+20, then calculate to get d=60. hope this helped! :)
