The average of the three numbers, 2, 3, and x-1 is n. what is the value of x in terms of n?

the average of a dataset is simply the "arithmetic mean", and is just the sum of the data items divided by how many items are there.

well, in this case we have 3 items, 2, 3 and (x-1), so, to get their average, we sum them up and divide them by 3, but we already know that's n, well

282 6/7 cm^2

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:
