)find a rational number and an irrational number that are between 7.7 and 7.9. include the decimal approximation of the irrational number to the nearest hundredth.

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:

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.
