You want to find x number of Kg worth $6.60 per Kg mixed with 10 Kg of nuts worth $8.50. So, you construct the equation $6.60x + $8.50(10) = $7.10 (10+x). This may seem confusing, but I'll try to make sense of it. There are $85 worth of nuts in the mix ($8.50 per Kg times 10 Kg) You want to add to that an x amount of Kg costing $6.60 per Kg. And you want the final mix to equal $7.10 per Kg. This made sense to me the most when I was learning these types of problems. YOU WANT THE TOTAL AMOUNT OF DOLLARS SPENT DIVIDED BY THE KG TO EQUAL $7.10. The left side of the equation I have given you is the cost in dollars of the mix, and the right side sets that equal to $7.10 dollars per Kg times total Kg of the nuts. Solve for x. You should get 28 Kg for x. Good Luck!

a million) 10 - 4 = 6. x + 3x = 6 4x = 6 x = a million.5 a million.5 km to first station, 4.5 from there to very last station. 4.5/a million.5 = 3. 2) 40/3 = 12 r4, 10 r10, 8 r16, 6 r22, 4 r28, 2 r34, or 0 r40 so that you may have 12 communities of triplets, with 4 little ones left over, making an allowance for 2 pairs of twins (4/2 = 2). you may also do 10 vacation. 5 tw., 8 vacation. 8 tw., 6 vacation. eleven tw., 4 vacation. 14 tw., 2 vacation. 17 tw., or no triplets and 20 pairs of twins. desire it rather is wise. 3) a) trend is situations 4, then divided with the help of two. a million/4 x 4 = a million a million/2 = a million/2 a million/2 x 4 = 2 So a million, then a million/2, then 2. b) The trend is divide with the help of three. -2/3 = -2/3 (-2/3)/3 = -2/9 (-2/9)/3 = -2/27 So -2/3, then -2/9, then -2/27. proper answer must be well known.

The answer seems to be 28 kilos of cashews need to be mixed with 10 kg of pecans.
28 kg @ $6.6 per kilo gives a price of $184.80
10 kg @ $8.5 per kilo gives a price of $85
Total price is $269.80 divided by total weight of 38 kilos gives an average of $7.10 per kilo.

6.6x +10*8.5 = (x+10)*(7.10)
6.6x + 85 = 7.1x + 71
subtract 6.6x both sides
85 = .5x + 71
subtract 71 from both sides
14 = .5x
multiply both sides by 2
x = ___________________
u solve from here
