Answer:
35
Step-by-step explanation:
M=5J
J=M/5
42=6J
42/6=7
Jullian is 7
7x5=35
Mary is 35
35+7=42
The answer is C because you divide the P so you get KP=AR then you finish the rest
Answer:
M(6,5) and G(2,9)
Step-by-step explanation:

B(3,6)
C(9,4)
m = [(3+9)/2 , (6+4)/2]
= (6,5)
M(5,9)
H(8,9)
G(x,y)
[(x+8)/2 , (y+9)/2]=(5,9)
(x+8)/2 = 5
x+8 = 10
x = 2
(y+9)/2 = 9
y+9 = 18
y = 9
G(2,9)
