I believe the answer is x=4
Yes it is greater than 1/2 because 1/2 is worth 50 while 3/5 is 60
You worked 5:15. From 6:45 to 12 is 5:15 then as you finish at 12:30 you just have to add 30 minutes to 5:15
135000/6000=X
22.5=X
So this building would need 23 fire extinguishers <span />
X = [14 -13]
It wants you to solve x + b = c for the first set (b=8, c=22) then solve it for the second set (b =4, c = -9). Then you put those answers in the same places that those numbers were
