Answer:
k<9/10
(I don't have the proper equality sign on my phone and it's too much work for me into input the proper inequality each time loll)
Explanation:
3/10>k-3/5
1)First subtract K to get it to the right side of the inequality
3/10-k>-3/5
2)Second, you subtract 3/10 in order for the inequality to be alone.
-k>-3/5- 3/10
3)Add both of the negative numbers of the right side so it's only one number. However, first you must multiply 3/5 by 2/2 in order to make both denominators(the bottom half of the fraction) equal in order to correctly subtract.
-k>-6/10-3/10
-k>-9/10
4)You divide by -1 because you cannot leave a variable negative which whenever your divide in an equality: YOU MUST ALWAYS FLIP THE SIGNS
Thus, k<9/10
