Since 27y is a factor of 54y3, it is automatically the GCF.
9(x - 3y)
Factorising 15x-27xy gives 3x (5 - 9y).Factorising is to express a number or expression as a product of factors.When factorising always look for common factors. To factorise (15x-27xy) look for the highest factor between the two terms (3x). 15x - 27y = 3x (5 - 9y)
There is a simple trick to solving these types of problems. Let the two numbers you're trying to find be "x" and "y".x + y = 40x - y = 14Add the equations.2x = 542x/2 = 54/2x = 27Now replace "x" in the equation with the new found value.27 + y = 4027 - 27 + y = 40 - 27y = 13.Now replace both "x" and "y" in the equation to check your answers.27 + 13 = 4027 - 13 = 14.Therefore your two numbers are 27 and 13.
Since 27y is a factor of 54y3, it is automatically the GCF.

~(3)-27y=(36)/(1000)Reduce the expression (36)/(1000) by removing a factor of 4 from the numerator and denominator.~(3)-27y=(9)/(250)Since ~(3) does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting ~(3) from both sides.-27y=-~(3)+(9)/(250)Divide each term in the equation by -27.-(27y)/(-27)=(-~(3)+(9)/(250))/(-27)Simplify the left-hand side of the equation by canceling the common terms.y=(-~(3)+(9)/(250))/(-27)Simplify the right-hand side of the equation by simplifying each term.y=(250~(3)-9)/(6750) y=0.06
