Answer:
<h2><u><em>
-8</em></u></h2>
Step-by-step explanation:
Solve equation
-8n + 7 * (8 + 3n)= -16 + 4n
-8n + 56 + 21n = -16 + 4n
13n + 56 = -16 - 56
13n -4n = -16 - 56
9n = -72
n = -72 : 9
<u><em>n = -8</em></u>
Answer:
14.4 acres for corn (if you need to round, it's 14 acres.)
Step-by-step explanation:
40% = 19.2 acres
20% = 9.6 acres

Answer:

Step-by-step explanation:
Since we're looking at perpendicular lines, the slope of the new line is the reciprocal of the original line.
So the slope of our new line is 
So far, we are looking at 
Now we need to find the b value by plugging in the given point.

So the final equation is 
Answer:
18lbs of Mexican Shade Grown coffee
Step-by-step explanation:
Since this is a ratio problem and we are given three values and one variable x (pounds of Mexican Shade Grown coffee needed) we can use the Rule of Three to solve this problem. In this rule we simply multiply the diagonal available values and divide by the third value to get the value of the variable, like so...
90lbs Gazebo <=====> 27lbs Mexican Blend
60lbs Gazebo <=====> x lbs Mexican Blend
(60 * 27) / 90 = x
1620 / 90 = x
18 lbs = x
We need 18lbs of Mexican Shade Grown coffee blend to mix with the 60lbs of Gazebo blend
