It's the last choice. In the top row you have the 1's that are the coefficients on the x and the y, and the solution for that equation is 21; in the second row you have the 5 from the x and the 4 from the y and the solution for that equation which is 20. I'm more used to writing them down instead of across, but there you have it anyways
Answer:
Step-by-step explanation:
multiply each variable's exponent by 2
(5x^2y^3)^2=5^2x^(2*2)y^(3*2)
simplify
5^2x^(2*2)y^(3*2)=25x^4y^6
Answer: 6/15 (2/5)
Step-by-step explanation: Since the problem says 3/5 of the recipe, you have to multiply. 'Of' means to multiply. Multiply both of the fractions across, first the numerators, then the denominators. You will get 6 as your numerator and 15 as your denominator. Reduce the fraction by 3, and your final simplified answer is 2/5.
Hope this helps!
