Kim ran total 7.1 miles.
Further explanation:
Front end estimation is the specific technique for rounding off numbers to estimates sums and differences. The numbers to be added or subtracted are rounded off to nearest one, tenth and hundredth.
So in the given scenario, we will round off to the nearest tenth.
So,
2.76 miles will be rounded off to 2.8 as the number right to the digit 7 is greater than 5, 7 will be rounded off to the next digit.
2.34 miles will be rounded off to 2.3 as the number right to 5 is less than 5, so 3 will be as it is.
1.97 miles will be rounded off to 2.0 as the number right to 9 is greater than 5 so it will be rounded off to the next number.
So, after estimation

Answer:
7×26=182
Step-by-step explanation:
I'm pretty sure that's the right answer but I just multiplied 26 by 7. Hope that helped!
Answer:
umm it should be (2×a)+(2×b) in equation
If you are solving for a: it equals 3
distribute: 5a + 5=2a +14
get rid of extra number on one side: 5a=2a +9 (subtract 5 from both sides)
get rid of the other variable: 3a=9 (subtract 2a from both sides)
divide to isolate a: 3a/3=9/3 (divide by three on both sides)
answer= a=3
Answer:
The greatest number of rows that can be planted, and have nothing left over, would be 3
Step-by-step explanation:
Find the greatest common factor (gcf) of 15 and 9
15: 1 3 5 15
9: 1 3 9
In this case, the gcf of 15 and 9 would be 3.
