The expression is 8x-(5x+8)
The simplifies is 3x-8 because 8x-(5x+8)=8x-5x-8 and 8x-5x=3x
Let's start out with what we do know:
We have a 5.2L pitcher and 0.4L glasses and we want to know how many glasses we can fill with the 5.2L pitcher of water.
To answer that, we need to divide 5.2L by 0.4L in order to get the number of glasses (the number of 0.4L glasses that can go into a 5.2L pitcher)
So our equation will look like this:

where n = number of glasses
so by doing that division we get:

Notice that the L's cancel out leaving us with a plain number.
So a 5.2L pitcher of water can fill up
13 glasses!
Answer:
I would say D
Step-by-step explanation:
<GHK and <KHI are supplementary and both adds up to 180 degrees. Since it's a right angle, both of them equal 90 degrees and therefore are equal to one another
Obtuse isosceles triangle.
x = 110 degrees.
Since it's greater than 90, and less than 180, it's classified as an obtuse isosceles triangle.
Hope this helps. - M
