The midpoint is the average of the endpoint coords. If (x,y) is F, then -6=(-14+x)/2 and 7=(13+y)/2. -14+x=-12 so x=2, and 14=13+y, so y=1 and F is (2,1). so the answer is (2,1)
P= 2.5m + 35 (replace p with 115) 115= 2.5m + 35 (subract 35 from each side) 115 - 35 = 2.5m 80 = 2.5m (divide 2.5 from each side) 80/2.5= 2.5m/2.5 32 = m
