A. A fish is 12 meters below the surface of the ocean. what is its elevation? B. A sea bird is 18 meters aboove the surface of the ocean. what is its elevation? 3. If the bird is directly above the fish, how far apart are they?

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:

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
