No they're not proportional, and it's four*.
4/2 = 2
20/6 = 3.333333333334 or 3 1/3
There would be 3 2/12 left.
2/3 x 1/4 = 2/12
Hope this helps!
Sorryyyy :C
Answer:
10 pounds.
Step-by-step explanation:
Let x pounds be the amount of mixed nuts we require.
Amount of peanuts in this mix = 0.70x pounds. Amount of peanuts in the 20% mix = 0.20*15 = 3 pounds.
So we have the equation:-
0.70 x + 3 = 0.40(x + 15)
0.70 x + 3 = 0.40(x + 15)
0.70x + 3 = 0.40x + 6
0.70x - 0.40x = 6 - 3
0.30x = 3
x = 10.
