Answer:
The answer is 9.
Step-by-step explanation:
I had the question on one of my quizzes.
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
When rounding the 4 you look to the right of the number, which is the 4, and if the number is higher than 5 you would change the 4 to 5.
Therefore: 71.5
You most likely will win a token. you have the advantage as the most they can win is 1 token if you lose, but you can win 3 tokens.
