<span>Changing the grouping of the addends should not change the sum, according to the associative property of addition. You might group them differently with (50 + 3) + 47, so that you have 50 + (3 + 47). You might not regroup them with (16 + 4) + 5 rather than 16 + (4 + 5).</span>
First you’d look for ones units that add up to 7, so in this case (5)4 and (6)3
Add 54 and 63 to get 117
Subtract 117 from 177 to get 60
25 and 35 equal 60 (I just know that from common knowledge I have no idea how to explain that in words)
So 25 + 35 + 54 + 63 = 177
Answer:240 miles
Step-by-step explanation: the reason they have 240 miles left to drive is because on the first day they drove 365 miles so you would subtract that by the total and you get 971 miles then you subtract 421 miles witch is what they drove on the second day by 971 and you get 550 and then you subtract 550 by 310 miles witch is what they drove on day 3 and then you get 240 miles.
