1. No
2. Because if you round 435 to the first digit 4 which is the 100s then it gets you 400 because it rounds down. Then you have to round 368 to it’s first digit 4 which is also the 100s, that gets you 400 because you round up.
400+400=800

Answer:

700 is not a good estimate.

Step-by-step explanation:

700 is not a good estimate. This is because 400 + 300 is already 700, and 30 + 60 is 90. 700 + 90 is much more closer to 800 than 700, so 700 is a bad estimate.
