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))
Answer:
9.375 inches burned in 7.5 hours
Step-by-step explanation:
To find how much burns in an hour, we need to divided 55 by 44, which, when calculated, is 1.25 inches
So 1.25 inches of the candle burns each hour
So now we multiply 1.25 by 7.5
1.25 x 7.5 = 9.375
Thus, the amount of candle that burned in 7.5 hours is 9.375 inches
Simplify the fractions 7/8 and 2/3 find the common denominatior which would be 24. so 2 times 8 = 16 and 7 times 3 = 21 so 3 16/24 and 5 21/24 is 8 24/24 which would be 9
The answer is 9
4/9 x 21/6 is this what you’re asking?
If so the answer is 1 5/9
