Answer:
the answer is -3ab + 6a - 8
Step-by-step explanation:
<u>All you do for this question is cross multiply and divide
</u> <em></em>is over of = x over 100
360/x = 150%/100
<u>3600/150= 24</u>
x=24<u>

Its a bit hard to read your question but it looks like its a mixture of 12% and 17% solutions forming a 14% solution.
This is essentially like a molarity question. The total volume must be ten, and the average the %s must be 14.
The answer is 4 gallons of 17% and 6 gallons of 12%
Let's say Set A = {1,2,3}, Set A can have subsets of:
{1}, {2}, {3}, {1,2}, {1,3}, {2,3}
This is 6 subsets.
