Answer:
All the 3 expressions are equivalent.
Step-by-step explanation:
1/2 ( x + 4 )
= x/2 + 4/2
= x/2 + 2
x/2 + 2 is same as 2 + x/2
The inequality you require is
The number of bottles left at the end of each day is 48 - 3x. So it is:-
48 - 3x < 10
Solving the inequality to find the last part of question:-
-3x < 10 - 48
-3x < -38
x > 38/3 = 12 2/3
So answer is 13 days.
The given answer would be five
