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

 

M - 16 = J + 16

 

Substitute 2J for Mary's age

 

2J - 16 = J + 16

2J - J - 16 = 16

J = 16 + 16

J = 32

 

Jerry is 32.

Mary is twice as old as Jerry.

Mary is 2(32) = 64

The rays OM , ON , and OP in the figure, coincide at time t=0. At the same instant of time OM and OP rotate in the plane about p
Lilit [14]
OM and OP will coincide a second time after 120 seconds. You could visualize it as ray OP moving at 3 degrees/second relative to OM.
Using this visualization, we find that OM makes 30*60*3/360 rotations (minutes * 60 * rotational speed/360 degrees in a rotation), which is 15, and that OP makes 30*60*6/360 or 30 rotations, which is 15 more than OM.
