The answer will be B! I hope this helps!
What form is DCAB? and I do not see the point Đ
It’s 76 meters hoped it helped!
First of all, don't let "b" confuse you. Know that b = 5/6k = -10, so all you really have to solve for this problem is
.
Before anything else, you have to isolate k. Do this my multiplying both sides by the reciprocal of 5/6.

The 6/5 and 5/6 cancel each other out, so we are left with 
--> 
---> 
So k = -12.
Hope this helped. Good luck.
