It's 12 because if you divide 6 by 0.5 you should get 12, so basically use the opposite operation.
Hope that helps!
The midpoint of these two points is (-1, 8).
In order to find the midpoint, you must take the average of each part of the coordinates. You do this by adding them together and dividing by 2. We'll start with the x-coordinates.
(-1 + -1)/2 = -1
Now we'll use the y-coordinates.
(10 + 6)/2 = 8
This gives us the ordered pair of (-1, 8)
X = 32 because 100 / 4 is 25, which would make the numerator for x 32
That means they have a common denominator. Hope this helps!
Well all triangles have an area of 180 degrees, therefore X=39 because 102+39=141 and 180-141=39.
