Answer: The value of k is 40.
Step-by-step explanation:
Since we have given that
28 is 12 less than k.
It means if we subtract 12 from k we would get 28.
12 Less than k means k-12,
'is' is used for equality.
Mathematically, it is expressed as
[tex]k-12=28\\\\k=28+12\\\\k=40[/tex]
Hence, the value of k is 40.
