Answer:
24
Step-by-step explanation:
21 times 8 is 168, and 168 divided by 7 is 24, therefore she would need 24 to give among 21 friends if she still wanted to have 1/8 left over.
To simplify the given equation, you want to combine like terms. Since both terms have x^8, we can add the coefficients and leave the x^8
3x^8-7x^8 (do 3-7)
=-4x^8 so the answer is C
Hope this helps
I think it is 200. I apologize if that is not the answer.
Answer is <span>4%
450 * 7 * i = 126
3150 i = 126
i = 126/3150
i = 0.04
0.04 = 4%
