Answer:

Step-by-step explanation:
We begin with the inequality: 
We need to solve for x. This means that we need to subtract 150 from each side and then divide each side by 750. Then we need to simplify.

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.
I am sorry but I do not see the underlined digit, but I will put it this way. 7 in the thousands place is worth 7000, 2 in the hundreds place is worth 200, 7 in the tens place is worth 70, and 0 in the ones place is worth 0.
Hope this helped!
