Combine like terms. 3w-3w=0. 8+2-8=2. So the answer is 2. I hope this helps!
        
             
        
        
        
Answer:
37.5 percent
Step-by-step explanation:
Well, there are 25+15=40 total people. Since there are 15 children, the percent is 15/40, which is equal to .375
Because percent is by hundredths, multiply by 100 by moving the decimal to the right twice, and you have a percentage of 37.5.

Answer:
y= 1/2x + 1
Step-by-step explanation: 
Refer to y=mx+b, m=slope and b= y-intercept
First, you find the slope: you can find the slope by finding the rise over run between two points. Rise= 1, Run=2. The slope is rise/run (rise over run), so the slope would be 1/2 (one half). 
Next, find the y-intercept. It is where the line touches the y-axis. Here, it would be 1. 
Finally, put these in y=mx+b form:
y=(slope)x+(y-intercept) ---> y= 1/2x + 1
I tried my best to explain everything, I hope you found this helpful!
