A ray only has one endpoint,
Point is not a length.
Since Sidney describes the ruler as a length of plastic that starts at 0 and continues on to 12 inches, she is using the line segment geometric term.
You need to add everything, the answer is D
Answer: 
Step-by-step explanation:
In order to solve for "x", we must remember the following properties:
- The Subtraction property of Equality states that:
If
, then 
- The Division property of Equality states that:
If
, then 
Therefore, knowing these properties, we can solve for "x" to find its value.
First, we need to subtract
from both sides of the equation. Then:

And finally, we can divide both sides of the equation by 6. Then we get:

Answer
36 pies
Step-by-step explanation:
to find out how much one pie costs we divide the profit made by the number of pies sold, or p/n = cost of 1 pie
from this we can conclude that 1 pie = $4
to find how many pies were sold we just plug back into the equation
so: $144/n = $4 and from this we get 36 pies
