Mike jogged 6 laps around a 0.25-mile track on mondat and 7 laps on tuesday. how many miles did he jog on monday and tuesday combined?

All you have to do is add up the number of laps and multiply that by the distance for each lap so its (6 +7)*0.25.

6+7=13
13*0.25= 3.25 miles
ANSWER= 3.25 miles

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
