Answer:
Step-by-step explanation:
Let (x,y) be midpoint of P(3,4) & Q(5,−2)
Midpoint formula for two points (a,b) and (c,d) is
(x,y) =(
2
a+c
,
2
b+d
).
x=
2
3+5
=4
y=
2
4−2
=1
∴ (x,y)=(4,1)
Answer:
8/15
Step-by-step explanation:
the denominators are different so you need to find the lowest common multiple which is 15
you times 3 by five so you have to change the 1 into 5
you times 5 by three so you have to change the other numerator to 3
so it becomes:
5/15 + 3/15= 8/15
