In this kind of problem the only thing you have to do is distribute all of the solution to see which one does not end up the same as the original.
The answer is 28/5, just make it a fraction for both of them then subtract
Answer:
3.5 (D)
Step-by-step explanation:
focusing on the right side of the decimal, 5 rounds 5 to 6. 6 rounds 4 to 5. Anything 5 or above rounds up! So the .5 rounds 4 to 5, making the answer 3.5. So sorry if this doesn't make sense, its kind of hard to explain.
Another way to word this ( if it helps)
The product of 15 and k is 45
So 15 times k equals 45
15k=45
This would be the equation- if we need to solve it
Divide both sides of the equation by 15 to isolate k
k=3
