50 cents plus 27 nickels equals 1.85
If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)
Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .
[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []
27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m
<u><em>Length of Fence = L = 780m + 2.7m = 782.7m</em></u>
Answer:
-3/2, -1
Step-by-step explanation:
Each coordinate contains one 
value and one 
value, 
.
If we work out the midpoint of each of these individually, it makes it much easier to find the midpoint of the line.
Let's take the values first. Our first value is -4 and our second value is 1. Imagine the integers between -4 and 1 laid out in a sequence:
If you take the middle value of this sequence, you get the midpoint of the values.
In this case, the middle is between values -2 and -1, leaving us with a midpoint of -1.5. This as a fraction is 
.
Now let's look at the values. Our first value is 2 and our second value is -4. Again, let's imagine those numbers laid out in a sequence:
Here, the middle of these values is -1, and this is the midpoint of the values.
So if we put these two values in a coordinate, we get the midpoint of the line.
In this case, we get 
.
