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.
-1/2 is rational, have a good day
Answer:
99000 meters.
Step-by-step explanation:
We have the swimmer going at 50 m / s, and we want to know where he is going in 33.3 minutes.
The first thing is to pass the time from minutes to seconds, we know that 1 minutes is 60 seconds, therefore:
33.3 min * 60 s / 1 min = 1998 seconds
Now to know the distance is to multiply this time by the speed they give us, like this:
1998s * 50m / s = 99900 m
Which means that in that time and at the speed of the swimmer, he has traveled 99000 meters.
Answer:
(D)=..take 18% of $50 which is $9.00
