Answer:
10/50 = <em><u>20%</u></em>
20% experimental probability
1/5 experimental probability
17 years
Step-by-step explanation:
1200/3z = 8
400=8/3 year for each building
they take 8
1600 is 2/3 year for each building
2/3 times 25 is 16.666
Step-by-step explanation:

No, there isn't a more efficient way to solve this system.
Yes, a more efficient way is to multiply the first equation by 4, add to eliminate y, then solve for x.
Yes, a more efficient way is to multiply the first equation by −4, add to eliminate y, then solve for x.
