Answer:
700
Step-by-step explanation:
For this one I'll do estimates. 271 estimated would drop down to 270. And 425 would bump up to 430. Adding 270 and 400 you would get a round number of 700!
Hope this helped.
It would be the last graph because at the x-intercept, it crosses the 5
18+21=39
33+49=82
Just add them together
A+7=0
A+7-7=0-7
A=-7
B+3=7
B+3-3=7-3
B=4
