Well if you divide 7 divided by 12 you get 0.583 which you can round however you wish but I am not sure if that’s what you mean
<span> -k - (-8k) = -k + 8k = 7k</span>
In the problem of insufficient data quantities. I can get a general solution.We know that tangent to a circle is perpendicular to the radius at the point of tangency. It's mean that triangles LJM and LJK are rights.
Let angle JLK like X.
So, angle JLM=61-x.
And it's mean that by using right triangle trigonometry
Radius MJ = LM*cos(61-X)
7/12 times 4 is 2 1/3. So 2 1/3 inches each week
