1) Find the coordinates of the midpoint of the segment whose endpoints are ZT-11, 3) and Q[11.-2)
A) (5,0)
B) (5.5, 2.5)
C) (0,5)
D) (4,4,5)

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
