Answer:
The amount of water must be added to this task = 60 
Step-by-step explanation:
Let amount of water added = x 
Then from the given conditions
A chemist would like to dilute a 90-cc solution that is 5% acid to one that is 3% acid. So
90 (0.05) = 0.03 ( 90 + x )
4.5 = 2.7 + 0.03 x
0.03 x = 1.8
x = 60 
Therefore the amount of water must be added to this task = 60 
Answer:
sam did the most
Step-by-step explanation:
let's find box packed per day
sam - 15 boxes in 5 days
so 3 boxes in 1 day
Dylan - 60 boxes in 4 weeks and 2 days
that is 60 in 30 days
that will make 2 boxes in 1 day
270 / 3 ( (4 - 3) 3 - (-9) ) - 53
270 / 3 (1 x 3 - (-9) ) - 53
270 / 3 (3 + 9) - 53
270 / 3 x 12 - 53
In PEMDAS, with multiplication and division, you must go left to right, not multiplication then division.
90 x 12 - 53
1080 - 53
1027 is your answer
