15 minutes is one quarter of an hour, so the number of people accommodated in an hour would be 4 x 55 = 220 people per hour
The inequality would be x > 453 because any year after he died would be more than the year he died.
Also, if it helps, I think of inequalities as an alligator's mouth, trying to eat the bigger quantity.
Hope this helps!
For all of the questions? Because
6x6=36
1x1x1=1
5x5x5x5x5x5=15,625
12x12=144
27x27x27x27=531,441
6^4=1296
0.5^3=0.125
(1/8)^2= 1/64
The answer is y=3+7x i think not sure
