Curly and Larry like to have their orange squash made to the same strength. Unfortunately, Moe has put 25 ml of
squash with 175 ml of water in Curly's glass and 15 ml of
squash with 185 ml of water in Larry's glass. How many
millilitres of the mixture in Curly's glass must be put into
Larry's glass so that they end up with drinks of the same
strength?

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.
