4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5
n = 1/2
Associative property is when you move the grouping symbols: ( and )
So the answer is B.
Answer: the third option. Show the midpoints are ( (a + b) / 2 , c/2 )
That is because, the two first statements are true because the figure is a parallelogram.
Given that the lines MP and QP are congruent, if they are bisected the midpoints are the same, which is what Hiroshi has to show.
