Answer:
+7
Step-by-step explanation:
Yes it is.
The common difference is +7
Steve ran 11 miles
let the distance Steve ran be x
Then distance Kevin ran is x + 4 ( 4 miles more than Steve )
x + x + 4 = 26 ( the sum of their distance is 26 )
2x + 4 = 26 ( subtract 4 from both sides )
2x = 22 ( divide both sides by 2 )
x = 11
Steve ran 11 mies and Kevin ran 11 + 4 = 15 miles
check 11 + 15 = 26
The answer is f because if you find the average between 78 and 62 you get 70
get a common denominator which is 24
3 7/8 = 3 21/24
6 /4 = 6 6 /24
3 21/24 - 6 6 /24
big number minus small number take sign of larger
6 6/24
- 3 21/24
-------------
5 30/24
3 21/24
--------------
2 9/24
2 3/8
the sign of the larger is negative
-2 3/8
11.25/375 = 0.03 which is 3%
