Mrs. Oropallo has a cool club. It cost $10 to join the club plus $2 per week. What would be an expression to represent the cost of joining given that "w" represents
the number of weeks?

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 is : muchas/tipicas

have a nice day!
