J, P, and L can each eat ice cream at respective rates of in gallons of ice cream per hour (gal/hr).
We're given that
We want to find . Subtracting the second equation from the third gives
so J can eat 2 gallons of ice cream in 3 hours, or 2/3 of a gallon per hour, so that it would take her 3/2 hours, or 1.5 hours, to eat 1 gallon on her own.
So basically are doing keep change flip of ((x^2)/(x-1))/((3x^2)/(x+4))
keep ((x^2)/(x-1)) change the division symbol (/) to a multiplication symbol (*) and flip the denominator ((3x^2)/(x+4)) to ((x+4)/(3x^2))
now we are multiplying ((x^2)/(x-1)) by ((x+4)/(3x^2)).
((x^2)/(x-1))*((x+4)/(3x^2))
multiply the numerators and then multiply the denominators to get
((x^3)+(4x^2))/((3x^3)-(3x^2))
let's now extract x^2 from the numerator and 3x^2 from the denominator to get ((x^2)(x+4))/((3x^2)(x-1)
now we can simplify it down to (x/3)((x+4)/(x-1))
I don't understand your question? If you reply back to me I can help you.
