Answer:
6:50
Step-by-step explanation:
The bell that rings every 10 min will ring at 6:00, 6:10, 6:20,6:30, 6:40, 6:50
The bell that rings every 25 min will ring at 6:00, 6:25, and 6:50
K = F + 459.67
Subtract K on both sides:
0 = F - K + 459.67
Subtract F on both sides:
-F = -K + 459.67
Divide each term by -1 so that the variables are positive:
F = K - 459.67
-10x + 1 + 7x =37
-10x + 7x = 37 - 1
-2x = 36
X = 36 / -2
X = -18
Answer is x = -18
I think this is the answer
