Joe's Painting: 20x + 100 = y
Steve's Painting: 15x + 120 = y
x = hours worked
y = total income
We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:
20x + 100 = 15x + 120
First, we have to move the 100 by subtracting it from both sides.
20x = 15x + 120 - (100)
20x = 15x + 20
Then, we need to move the 15x by subtracting it from both sides.
20 - (15x) = 20
5x = 20
Lastly, we need to divide 5 from both sides.
5x = 20/5
x = 4
Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.
When finding the mean you add up the numbers that are needed to find the mean and divide them by the amount of numbers you added. For example question 5 you will add 58+58+62+55+49+48 which will equal 330 and then divide it by 6 because there are 6 numbers which is 55.
Answer:
Round out to the nearest 10th say 5 it would stay 5 unlike 8 would round to 10
