In one year a school uses 13,470 pieces of white paper,5870 fewer pieces of blue paper than white paper and 3500 fewer pieces of yellow paper than blue paper. how many pieces of paper does the school use in all?

25,170 pieces of paper

Step-by-step explanation:

13,470-5870=7600 blue

7600-3500=4100 yellow

13470+7600+4100=25,170 pieces of paper

the mean and mad

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
