A chef had a dozen eggs and used some in an omelette. He had 5 left. Write an equation to find the number of eggs (x) he used for the omelette. What is the number of eggs in each omelette?

step-by-step explanation:

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:

false

inverse variation is not exponential

9.27 =9 5/18  

9.27 =9 3/11
