Answer:
x = 9/25, y = 7/25, z = 4/25
Explanation:
step 1: solve for y in first equation to use substitution
y = -2x + 1
step 2: insert into second equation to eliminate y variable and work with two variables
3(-2x+1) + z = 1 (now distribute)
-6x + 3 + z = 1 (bring over the -3)
-6x + z = -2
step 3: now left with -6x + z = -2 and x + 4z = 1, so eliminate z
-6x + z = -2 (multiply by 4)
4(-6x + z = -2)
-24x + 4z = -8
-
x + 4z = 1 (brought down third equation)
-25x = -9
x = 9/25
then just plug in x into the third equation to solve for z, followed by plugging it into the first equation to solve for y. you should end with y = 7/25 and z = 4/25
Answer: the amount of energy from light converted to the chemical energy of organic molecules PER UNIT TIME.
Explanation:
The correct answer is - all of these contributed.
The sediments in the lagoons come from multiple different sources. The rivers and streams from the mainland, the sediments brought by the wind, and even the ocean waves that manage to get over the spit occasionally.
The biggest influence in the deposition of the sediments in the lagoons though is by the rivers and the streams from the mainland. They carry sediments with them constantly, and the amount of those sediments is also on a high level, in fact they bring in so much sediments that they have actually built the lagoon itself.
The wind and the ocean waves that manage to get over the spit have much lesser influence in the total deposition of sediments, but still they do in some part, and it shouldn't be put aside.
The combination of the three different sources, with different types of sediments brought to the lagoon by each of them, gives the lagoons a beautiful and unique appearance.
