Michell has 8 coins witch are all quarters and nickles. in all, they're worth 80 cents. how many of each kind of coin does michelle have?

First, find the values of a quarter and a nickel. These are 25 and 5 cents.

Then, find the difference, it's 20 cents.

Multiply 5 or 25 by 8, and find the difference of that and 80.

Divide that by 20, and that's how much of the other coin you didn't use above to multiply.

Subtract 8 - 2 or 8 - 6 for the coin you did use.

So, 2 quarters, 6 nickels.

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
