What is the unit price of 4 bags for $3.24

$0.81

Step-by-step explanation:

If 4 bags cost $3.24 in total, then to find the unit price, or the individual price of each bag, all you have to do is divide the total amount of money by the number of items you are buying, which would look like this:

3.24 / 4 = 0.81

and that's our answer.

Each bag costs $0.81, which is the unit price.

Hope this helps :)

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

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.
