Nana's age: 10 years
Step-by-step explanation:
Here we call:
J = Jennifer's age
L = Laurel's age
N = Nana's age
We have the following information:
- Jennifer is twice as old as laurel, so
J = 2L (1)
- Laurel is 4 years younger than Nana, so
L = N - 4 (2)
- Nana is 2 years younger than Jennifer, so
N = J -2 (3)
Substituting (2) into (1),
J = 2(N-4) = 2N - 8
And substituting this into (3) and solving for J, we find Nana's age:
N = (2N-8) - 2
N = 2N - 10
N = 10
Which means that Jennifer's age is:
J = N + 2 = 12
And Laurel's age is
L = J/2 = 6

Answer:
Step-by-step explanation:
Note that closed dot means that it is included inside. Look at the direction of the arrow, it will give you the knowledge of which way the sign will face.
10) x ≥ -1, or (4)
Note that the point is at -1 (-1), The arrow is also traveling towards the greater side (>). Note that the dot is 'colored in', or closed. If the dot is closed, the number the dot is on is included inside, leading to the sign having an equal sign on the bottom.
11) -4 ≤ x < 2, or (2)
As stated above ≤ means <em>closed dot</em> (or included). x is greater than -4, and so -4 is ≤ x. However, note the dot on the 2. It is not colored in. This means that 2 is not included inside the solution, leading to the usage of <.

Yes, that's the definition of "midpoint."
