Answer:
2 1/4 days
Step-by-step explanation:
You could extend your table a bit to help answer this.
(days, hours)
(1, 24)
(1/2, 12)
(1/4, 6)
(2, 48)
Now, we observe that 54 hours is 6 more hours than 48 hours, so will be 1/4 day more than 2 days.
54 hours is 2 1/4 days
5(8x - 10) - 10x + 25(8x - 10) - 10x + 2
= (40x - 50) - 10x + (200x - 250) - 10x + 2
= 40x - 50 - 10x + 200x - 250 - 10x + 2
= (grouping like terms together)
= 40x - 10x + 200x - 10x - 50 - 250 + 2
= 220x - 298
