s = 2.5w + 10

Step-by-step explanation:

You have $10.00. Each week you save $2.50. The number of weeks you save w increases your savings s. Write an equation relating your savings s to the number of weeks you save w.

Your total savings (s) =

How many weeks you have been saving * how much you earn every week + the amount of money you already have.

So, the final equation should be:

w * 2.5 + 10 = s

Simplify.

s = 2.5w + 10

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.

3/20

step-by-step explanation:

well, there are 20 outcomes, and 3 of them you want. so, 3/20
