1. -6
2. 4
2. -1
The positive numbers will out rule the negative number. It's sort of like placing blocks over another set of blocks. :)
X+2y=1
2y =1-x
y= (1-x)/2
5x-4y= -23
By substituting the value of y in this equation
5x -4 {(1-2)/2} = -23
5x- 2 +2x = -23
7x= -21
x= -3
Now, let's find the value of y bu putting the value in any othe two equations
I'll use x +2y=1
-3 +2y=1
2y =4
y=2
So, the value of x and y is -3 and 2 respectively.
A) mean, mean is the average of all the number. To get the the mean/overall you add the the number and divide by the amount of numbers.
Answer:
25 silk leaves
Step-by-step explanation:
The opportunity cost would be what was normally stopped by doing something else, we have two scenarios:
First stage:
A combination of 60 silk roses and 80 silk leaves
Second stage:
A combination of 70 silk roses and 55 silk leaves
Therefore, comparing the two scenarios, by producing more silk roses, the amount of silk leaves is decreased, by the following amount:
80 silk leaves - 55 silk leaves = 25 silk leaves.
Therefore the opportunity cost is 25 silk leaves
