Answer:
5/6 books
Step-by-step explanation:
We know that Mark read 2 1/2 books last week. This week, he read a bit more with 3 1/3 books.
To find how many more books he read, we must subtract 2 1/2 from 3 1/3:
3 1/3 - 2 1/2
Let's convert these into improper fractions first:
3 1/3 = (3 * 3 + 1) / 3 = 10/3
2 1/2 = (2 * 2 + 1) / 2 = 5/2
Now, we have:
10/3 - 5/2
In order to subtract these, we must find a common denominator. For 2 and 3, the LCM is 6, so we can use that as our common denominator:
10/3 * 2/2 = 20/6
5/2 * 3/3 = 15/6
Finally, we have:
20/6 - 15/6 = (20 - 15) / 6 = 5/6 books
we know that
the equation of the circle is of the form
where
(h,k) is the center of the circle
r is the radius of the circle
in this problem we have
so
the center is the point 
the radius is 
therefore
the answer is
The radius of the circle is equal to
The answer would be 4 hundreds 3 hundreths

Let present age of Anne be x
Two years ago she was Jim's age which is 10 yrs she is now double that age
10(x-2)
10x-20
= She is now 20 yrs
