This is the way I do it to find the average.

10 girls times 70 = 700

15 boys times 80= 1200

700+1200=1900 all their scores

1900÷25 (number of boys and girls)=76 or 76%

All you do is divide 96 divided by 6. That is your equation. Then when you divide it, you find that he will put 16 on each shelf. All of the shelves will have the same number of books. The next one all you do is add all of them up and it will equal 43. So he has 43 dvd in total. Now if he wants to only keep eight of the dvds you subtract eight from 43. That equals 35. Now all you do is divide that by 5 to see how many he will give each friend. Once you're finished with that you find that he will give 7 to each friend.
So, the answers to each problem are 16 with the equation using distributive property 2(44 + 2) divided by 6 and 7.
I hope this helps:) Please give brainliest:)

Answer:

The average rate will be -11000 dollars per year.

Step-by-step explanation:

The price of a house in 2005 = $250,000

The  price of a house in 2010 = $195,000

at x₁ = 2005, f(x₁) = 250,000

at x₂ = 2010,  f(x₂) = 195,000

Using the formula to determine the average rate of change for the

house each year.

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                      = [195,000 - 250,000 ] / [2010-2005]

                      = -55000 / 5

                      = -11000

Therefore, the average rate will be -11000 dollars per year.

Describe and correct the error in determining which type of function the table represents.
topjm [15]

Answer:

<em>"Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>

Step-by-step explanation:

In reality, the table represents an exponential function instead of a linear function, since values on domain change arithmetically at constant rate, whereas values on range change geometrically at constant rate.

Correct phrase may be:<em> "Consecutive y-values change by multiplying previous value by a constant amount. So, the table represents an exponential function."</em>
