let L be <span>Lissette's age
and F </span><span>Francesca age
2 F - 3 = 13
2F= 16
F = 16/2 =8

First figure out his total bill by adding up what he buys.

Now subtract the discount of $20 since his purchase was above $100:
Answer:
The force on the book is 250N.
Step-by-step explanation:
Newton's second law states that the equation for the force is:

In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.
In this question:

So

The force on the book is 250N.
1. 208/x = 100/130
2. multiply both sides by x
3. 208 = 0.76923x
4. divide both sides by 0.76923
5. x = 270.4
Answer:
Option D.
Step-by-step explanation:
If two triangles ΔABC and ΔA'B'C' are similar then we take point C of ΔABC to find the transformation performed form C to C'.
Coordinates of C are (0, 3) and the coordinates of C' are (0, -1).
This shows that C is rotated 180° about origin to get the new coordinates as (0, -3) and then new coordinates were dilated by 1/3 which forms C' as (0, -1)
Therefore option D is the correct option.
