Answer:
10
Step-by-step explanation:
Since m||n the sum of given angles is equal to 180 (they are supplementary)
6x + 10 + 10x + 10 = 180 add like terms
16x + 20 = 180 subtract 20 from from both sides
16x = 160 divide both sides by 16
x = 10
You can see that there are 6 rock CDs, over a total of
So, the ratio of rock CDs over the total number of CDs is
Which is 15%.
So, yes, the answer is A

Answer:
18x^5 +28x^2
Step-by-step explanation:
20x^2 + 14x^5 + 8x^2 + 4x^5
Combine like terms
20x^2 + 8x^2 + 4x^5+ 14x^5
28x^2 + 18x^5
We usually write the highest power term first
18x^5 +28x^2
