B, Paco won the race. Juan’s time was 15, Packs was 12, Pedros was 13. And Brads was 17.
All you would have to do is look at the 2 in the place of the thousands which equals 2000, then look at the 2 that is in the place of the tens, which equals 20, so (this might get complicated) 2000/20 is... (If you need more help just tell me)
Answer: Place the runners into groups based on the seconds part of their finishing time (0:00–0:05, 0:06–0:10, etc.). Randomly select 2 of these groups, and survey every runner within the chosen groups.

Answer: ![x=58+57=115](https://tex.z-dn.net/?f=x%3D58%2B57%3D115)
![y=178-115=63](https://tex.z-dn.net/?f=y%3D178-115%3D63)
Step-by-step explanation:
Let x be the number of computers Grade 3 and grade 4 has and y be the numbers of computers the rest of school has.
Then, x= Grade 3 computers +Grade 4 computers.
![\Rightarrow\ x=58+57=115](https://tex.z-dn.net/?f=%5CRightarrow%5C%20x%3D58%2B57%3D115)
And y = Total computers - x
![\Rightarrow\ y=178-115=63](https://tex.z-dn.net/?f=%5CRightarrow%5C%20y%3D178-115%3D63)
Therefore, The equations can be used to find how many computers the rest of the school has.
![x=58+57=115](https://tex.z-dn.net/?f=x%3D58%2B57%3D115)
![y=178-115=63](https://tex.z-dn.net/?f=y%3D178-115%3D63)
