7y. the 7x cancels out and if u distribute, it's 7y.
In general, the statement 'a is subtracted from b' is written as
Therefore, 'A number is subtracted from 2' is written as,
The answer is 2-x
17mm is the answer.
To solve this:
1.) Find the radius of the entire pencil.
The radius of the graphite is .75 (half the diameter) and the thickness of the wood is 2, so 2 plus .75 gives you a total radius of 2.75.
2.) Using this radius, find the circumference of the entire pencil using the equation C = 2 • pi • r.
C = 2 • pi • r
C = 2 • 3.14 • 2.75
C = 17.27 (17 is the answer after rounding to the nearest millimeter)
42! The mean is where you add all the numbers!!
