Answer: 13 1/3

Step-by-step explanation: First find out how many times 6 goes into 80, (which is 13) then find the excess and put it over the original denominator (which would be 6), lastly you need to simplify the fraction which is 1/3.

80/6 = 13.33333

6 x 13 = 78

80 - 78 = 2

13 2/6 = 13 1/3

6 0

Answer:

13 $\frac{1}{3}$

Step-by-step explanation:

The closest multiple of 6 less than 80 is 13.

13×6=78

How many are left over?

80 - 78 = 2

$\frac{2}{6}$ remains, and this can be simplified to $\frac{1}{3}$

13 $\frac{1}{3}$

Hope this helps!! (I know it sounds a little complicated but it's easy to understand it with practice :)

The general equation of a circle is (x-h)²+(y-k)² = r². The equation of circle A is (x+4)²+(y+2)²=9.

<h3>What is the equation of a circle?</h3>

The general equation of a circle is given as,

(x-h)²+(y-k)² = r²

Where (h,k) is the coordinate of the centre of the circle, and r is the radius of the circle,

Given that the four points that lie on the circle are (-4,1), (-1,-2), (-4, -5) and (-7,-2), and also the centre of the circle is at (-4,-2). Therefore, the radius of the circle will be the distance between the centre of the circle and any point lying on the circle.

$\rm \text{Radius of the circle} = \sqrt{[(-4)-(-4)]^2+[(-2)-(1)]^2}\\\\\text{Radius of the circle} = \sqrt{(0)^2+(-3)^2}\\\\\text{Radius of the circle} = 3\ units$

Since the coordinate of the centre point of the circle is (-4,-2), while the radius of the circle is 3 units, therefore, the equation of the circle can be written as,

$[x-(-4)]^2+[y-(-2)]^2 = 3^2\\\\(x+4)^2+(y+2)^2 = 3^2\\\\(x+4)^2+(y+2)^2 = 9$
