<span> 5x + 6y= -12 7) x - 5y = 0 6) x +6y = - 42 8) 4x - 7y = -21 </span>
bus A takes 25 mins
bus B takes 35 mins
start at 8am
to find =lcm of 25 and 35
LCM of 25 and 35
5 /__25,35
/__5,7

=175 mins=8hr+175mins=10:55am
Ratio and proportion
2464/3200= x%/100%
cross multiply
3200x=246400
divide by 3200
x=77% is current
100%-77%= 23% decrease in circulation
hope this helps
