Answer:
Hermione has 16 marbles. Harry has 24 marbles.
Step-by-step explanation:
Harry = y + 8
Hermione = y
y + 8 + y = 40
2y + 8 = 40
2y = 32
y = 16
Hermione has 16 marbles.
Harry has 24 marbles because 16 + 8 = 24.
Harry has 24; Hermione has 16
2.5
The constant of probability is 16/6.4=2.5
n = 19/18
Given:
11/6 = n + 7/9
Find n
Subtract 7/9 from both sides of the equation
11/6 - 7/9 = n + 7/9 - 7/9
11/6 - 7/9 = n
(99-42) / 54 = n
n = 57/54
