Answer:
27x^6y^9
Step-by-step explanation:
(3x^2y^3)^3 = 3^3 * (x^2)^3 * (y^3)^3 =
= 27x^6y^9
Answer:
Take 1651 divided into 13 you get 127 so they can buy 127 posters . Then they sold them for 20 dollars a piece so take 20 times 127 which is 2,540 dollars that’s the money they got .
Answer:
x=4 and y=4

using simultaneous equations by elimination method
Answer:
10(x-3) is equivalent to 10x – 30
Step-by-step explanation:
<u>First you have to take everything of out the parentheses and then simplify if needed. </u>
- 10(x – 30) is not equivalent to 10x – 30 because, 10 times x is 10x, but 10 times 30 is 300. So, 10(x – 30) is not equivalent to 10x – 30.
- 10(x – 3) is equivalent to 10x – 30 because, 10 times x is 10x, and 10 times 3 is 30. So, 10(x – 3) is equivalent to 10x – 30.
- 10 + (x – 20) is not equivalent to 10x – 30 because, 10 minis 20 plus x are -10 + x. So, 10+(x – 20) is not equivalent to 10x – 30.
- 10(x – 20) is not equivalent to 10x – 30 because, 10 times x is 10x, but 10 times 20 is 200. So, 10(x – 20) is not equivalent to 10x – 30.
Answer: 10(x-3) is equivalent to 10x – 30
