The months where the difference in salinity of surface and bottom waters was the greatest was in April and September.

It should be noted that salinity simply means the accumulation of salt in land as well as water.
In this case, the months where the difference in salinity of surface and bottom waters was the greatest was in April and September.
This is because many events take place such as continuous flowing or river water into the sea, evaporation, and melting of ice.

2.1x + 4.2y = 14.7 is the same as x + 2y = 7 (divide both sides by 2.1)
-5.7x-1.9y=-11.4 is the same as 3x + y = 6 (divide both sides by -1.9)
Rearrange the first equation to get x = 7 - 2y and substitute into the second equation, 3(7 - 2y) + y = 6, 21 - 6y + y = 6, 5y = 15, y = 3
Substitute y = 3 into the first equation x + 2(3) = 7, x = 1
x = 1 and y = 3

Answer:
50 mm
Step-by-step explanation:
Using the proportion: 1mm/ 3m
<u>1mm</u> <u> xmm</u>
3m 150m
150/3= 50
1(50)= 50
x=50mm
