The answer is 2xy-2x you get this by combining like terms
The value of the following thingy is not correct
The answer is 10/3
The explanation 2 1/3 cu of flour/ 3 1/2 dozen of cookies = X unknown cu. of flour/ 5 dozen cookies
Cross multiply
3 1/2 X = 5 (2 1/3) Change the mixed numbers into improper.
7/2 X = 5 ( 7/3) Solve for "X." Multiply both sides of equation by reciprocal of 7/2, which is 2/7
(2/7 (7/2)X = 5 (7/3)(2/7) X= 10/3 =Just divide 10 by 3. You should get a whole number
If you want the common denominator, then 1/2 is 4/8. I hope that answers your question :)
