Answer:
the average of this new list of numbers is 94
Step-by-step explanation:
Hello!
To answer this question we will assign a letter to each number for the first list and the second list of numbers, remembering that the last number of the first list is 80 and the last number of the second list is 96
for the first list

for the new list

To solve this problem consider the following
1.X is the average value of the second list
2. We will assign a Y value to the sum of the numbers a, b, c.
a + b + c = Y to create two new equations
for the first list

solving for Y
Y=(90)(4)-80=280
Y=280=a+b+c
for the second list


the average of this new list of numbers is 94

Step-by-step explanation:
On a supply and demand graph you would see that the supply would meet the demand at the central point creating a secure system. However, this could change for the better or worse, compared to how "popular" the item is in the market.
2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
