Pretend you are teaching a friend how to find the circumference of a circle. Your friend isn’t even sure they know what circumference is. Write a narrative of what you would say to your friend to explain what circumference is and how you find it.

The circumference of a circle is the distance around the Outside of the circle.

The circumference of found by multiplying PI by the diameter of the circle.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
