Answer:
m = 10
Step-by-step explanation:
Given w is inversely proportional to m then the equation relating them is
w = 
← k is the constant of variation
To find k use the condition w = 8, m = 25 , then
8 = 
( multiply both sides by 25 )
200 = k
w = 
← equation of variation
When w = 20 , then
20 = ( multiply both sides by m )
20m = 200 ( divide both sides by 20 )
m = 10
That would be D. The first two would be fight (I think) except they don't include turning the calculator on. C is just plain wrong. D has all the right keystrokes.
1,655,000 maybe I not entirely sure sorry
I don't know what the graft is
