The percent of boys in the class is 40% because 16 + 24 = 40 (the entire amount of kids) 16 / 40 = .4 then move decimal twice to the right for percentage which gives you 40%
The answer is 40%
I hope this helped :)
Actually the answer is
-3x + 5y = 15
2x + 3y = -10
10 hours seems like the most reliable answer because it matches up the best
If 25% is 80, 100% is 320. 60% of 320 is 192.
