Answer:
19 km/h
Step-by-step explanation:
average speed = total distance / total time
in this case it will be 57/3 = 19 km/h
It would be a right scalene triangle.
hope this helped :)
-125g ^2 that’s what I got solving for it
Five laps? I don’t know if you meant to put that the track is a mile around, but if the track is a half mile around, an athlete would have to run 10 laps around the track to run 5 miles.
X=5/y, so x would be how many laps the athletes run, and y would be the length of the track. Hope this helps
Answer:
Answer below.
Step-by-step explanation:
1. a + 19 | 10 + (a + 9) = a + 19
10 + 9 = 19
a + 19
_____________________________
2. (C + 2/3) + 1/2 = C + 7/6
2/3 = 4/6
1/2 = 3/6
4/6 + 3/6 = 7/6
C + 7/6

3. 5 (4n) = 20n
5 x 4n = 20n
