You can start by drawing a number line and labeling it with eighths. ( 1/8, 2/8, etc.) Then you can place a dot on 3/8 and 5/8. From there, it's clear to see that 5/8 is greater than 3/8.
The solution set of 3x+5=x+2 is x=-1. This is because you want to get the variables on one side and the numbers on the other. you subtract x on both sides and subtract 5 on both sides. your equation then becomes 3x=-3. you then divide 3 on both sides and you get your answer of x=-1.
We can calculate the percent change dividing the change by the original amount of people attending the exhibit.
The increase is 298-152 = 146.
Then, we can calculate the percent change as:

There was a 96% increase in the number of people attending the exhibit.
The answer is 15 you would add all the numbers then divide them by the number of numbers given :3
