8(x)+8(2)
8x+16
8 divided by 16 = 2
We need 56 pints of the 55 % <em>pure fruit</em> juice and 84 pints of the 80 % <em>pure fruit</em> juice to prepare 140 pints of 70 % <em>pure fruit</em> juice.
<h3>How to use weighted averages to find the correct juice concentration</h3>
In this problem we have to use two kinds of juice with different concentrations. To get a certain concentration, we must adjust quantities of each kind and <em>weighted</em> averages offers a method that is easy to apply:
70 · 140 = 55 · x + 80 · (140 - x)
70 · 140 = 80 · 140 - 25 · x
25 · x = 10 · 140
x = 56
We need 56 pints of the 55 % <em>pure fruit</em> juice and 84 pints of the 80 % <em>pure fruit</em> juice to prepare 140 pints of 70 % <em>pure fruit</em> juice.

Answer: 99
Step-by-step explanation:
Answer:
-1/2
Step-by-step explanation:
Point L is at (-2,3)
Point M is at (2,1)
We can find the slope using
m =(y2-y1)/(x2-x1)
= (1-3)/(2 - -2)
=(1-3)/(2+2)
=-2/4
=-1/2
