Answer:
-7k = -45.5
Explanation:
You can solve this by plugging in the “k” to the problems that are listed.
If you were to plug 6.5 in for all those problems, you’d get:
-3(6.5) = -19.5
-1 + 6.5 = 5.5
-7(6.5) = -45.5
-2 + 6.5 = 4.5
So, in this case, looking at the ones I answered and looking at the problems listed, the correct answer would have to be -7k = -45.5.
