M = Mell
J = Jerry
M = 2J [Mell is twice as old as Jerry]
M - 16 = J + 16 [When Mell's age is subtracted by 16, and 16 is added to Jerry's age, their ages will be equal]
Since you know M = 2J, you can plug in/substitute 2J for "M" in the second equation:
M - 16 = J + 16
2J - 16 = J + 16 Add 16 on both sides
2J = J + 32 Subtract J on both sides
J = 32
Now that you know Jerry's age, you can find Mell's age:
M = 2J
M = 2(32)
M = 64
Mell is 64, Jerry is 32
Answer:
Step-by-step explanation:
Let J = Jerry's age
Let M = Mary's age = 2J
Substitute 2J for Mary's age
2J - 16 = J + 16
2J - J - 16 = 16
J = 16 + 16
Jerry is 32.
Mary is twice as old as Jerry.
Mary is 2(32) = 64

Melanie.
The possible ways of getting a 6 are (3,3), (2,4), (4,2), (1,5) and (5,1).
That is 5 ways.
The possible ways of getting a 7 are (1,6), (6,1), (5,2),( 2,5), (3, 4), (4,3).
That is 6 ways.
So Melanie made the better decision.
The answer would be 50%
You Would get this by dviding 36/72 which would give you .5 and then you convert that to a percentage
