If eight avacados cost $2.64, how much would five avacados cost? Do this in algebra, including your word problem setup and through solution check.

The algebra is simple.
Or is it?

x – 5 > 6 or 2 – x > 4
The compound inequality is equivalent to
x > 6- (-5) or 2-4 > x
which in turn is equivalent to
x > 11 or x < -2
solution: (-infinity,-2)U (11,infinity)

I have the solution on a graph line
but am not getting the solution checking besides the usual "plug in"

3/7x + 5/9y = 27

1/9x + 2/7y = 7
solve by any method:

27x+35y=(97)*27
27x+35y=63*27
27x+35y=1701
27x+35y-35y=1701-35y
27x=-35y+1701
27x/27=(-35y+1701)/27
x=63

27x+35y=2619
(27x+35y)+(-27x)=2619+(-27x)
27x+35y=97*27
y=27(-x+97)/35
y=0

solution check?
there are more than one?

Reader’s Digest ran a sweepstakes in which prizes were listed along with the chances of winning: $1,000,000 ( 1 chance in 90,000,000), $100,000 ( 1 chance in 110,000,000), $25,000 ( 1 chance in 110,000,000), $5,000 ( 1 chance in 36,667,000), and $2,500 ( 1 chance in 27,500,000).

a) Assuming that there is no cost of entering the sweepstakes, find the expected value of the amount won for one entry.
b.) Find the expected value if the cost of entering this sweepstakes is the cost of postage stamp. Is it worth entering this contest?
