Question 1143037: How many gallons each of 25% alcohol and 5% alcohol should be mixed to obtain 20 gal of 16% alcohol? That equals 3.2 gallons pure, checks.
Answer:
Step-by-step explanation:
Given: A bushel contains 4 pecks and a peck contains 8 quarts.
i.e. A bush = 4 pecks
A peck = 8 quarts

Let b = number of bushes and q = number of quarts
Number of quarts(q) in b bushes = 32b
hence, required equation:
which describes the relationship between the number of b bushels and the number of q quarts.
You need to clarify whether you need the x or the y or both
2x^3-2x^2+3x^2-3x-6x+6
