2x-8=12
First you add 8 to both sides...
2x = 20
Then you divide each side by 2...
x = 20
Done

Wrong things...
- did not do the same thing to the entire side of each side

how many pounds of nuts selling for $9 per lb and raisins selling for $3 per lb should a person combine to obtain 60 lb of a tra
marta [7]
Let n be the number of lbs of nuts.
Let r be the number of lbs of raisins.
9n + 3r = 60 * 5 = 300 .............(1)
n + r = 60
n = 60 - r ...............(2)
Plugging the expression for n in (2) into (1) we get:
9(60 - r) + 3r = 300
which expands to:
540 - 9r + 3r = 300 .............(3)
Simplifying and rearranging (3) we get:
-6r = -240
Therefore r, the weight of raisins = 40 lbs
and the weight of nuts is 60 - 40 = 20 lbs

640, 160, 40, 10,....
-Dominant- [34]
The pattern is dividing by 4 so it would be: 640 (divided by 4), 160 (divided by 4), 40 (divided by 4), 10 (divided by four), 5/2.
The next number would be 10/4 or 5/2 when simplified. (I’d go with 5/2 because teachers liked simplified numbers)
