For your party you purchased balloons for $.79 each. you spent a total of $11.85. about how many balloons were purchased?

Let us suppose the number of balloons purchased is x in number.

It is given balloons are purchased for $.79 each

Cost of x balloons = .79x.

Total amount spent on purchasing balloons = $11.85

Cost of x balloons = Total cost of balloons.

.79x=11.85

With x .79 is multiplied .Opposite of multiplication is division.

We perform the opposite operation both sides

Dividing both sides by .79

x=11.85÷.79

x=15

Total number of balloons purchased is 15.

step-by-step explanation:

hope this

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.
