In an 18-mile duathlon you run then bike 12 miles and then run again the two runs are the same distance find the distance of each run

3 miles.

Step-by-step explanation:

We have been given that in an 18-mile duathlon you run then Bike 12 miles and then run again.

The distance covered by running would be 18 miles minus 12 miles.

Since two runs are the same distance, so distance of each run would be 6 divided by 2.

Therefore, the distance of each run was 3 miles.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

c. side angle side. u shares the same sides
