n, n + 2, n + 4 - three consecutive even integers
n + 2 = 2(n + 4) - 6 |use distributive property
n + 2 = (2)(n) + (2)(4) - 6
n + 2 = 2n + 8 - 6
n + 2 = 2n + 2 |subtract 2 from both sides
n = 2n |subtract 2n from both sides
-n = 0
n = 0
n + 2 = 0 + 2 = 2
n + 4 = 0 + 4 = 4
Answer: 0, 2, 4.
<span>'x' can be anything. There's no information here to say that it must be
one thing or another. You can't find 'x', because there is no
equation.
You can probably simplify the fraction by doing some factoring, but
there's
no way to tell a value for 'x'. As long as 'x' is not -4, it can be anything, and
its value determines the value of the fraction.</span>
Mean simply means average
so just add them all up and divide by 5
22 + 37 + 49 + 15 + 71 = 195
195/5 = 39
mean = 39
