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

Answers to numbers (Somebody else do another half)
1. If I could do something I've never done before, it'd be sky diving. I would want to go sky diving for the thrill of falling and descending back to Earth from a great height. Also, trying new activities is awesome, so why not do as much as you can while you're still here?
2. Pollution is bad because it kills the environment and people around us. Pollution may muddy landscapes, poison soils and waterways, or kill plants and animals. Humans are also regularly harmed by pollution. Long-term exposure to air pollution, for example, can lead to chronic respiratory disease, lung cancer and other diseases.
3. If I could go back to any place in time, I would stay right where I am. The world is already bad enough with political issues, protests, fires etc. Going back in time would do nothing but change the flow and disrupt how the world is working.
The sociological perspective is a perspective on human behavior and its connection to society as a whole. It invites us to look for the connections between the behavior of individual people and the structures of the society in which they live. Typically, we tend to think of our society as just natural.
Answer;
Evaporation is when water vapor comes from liquid surface water, such as streams, lakes, rivers, and oceans. ... Transpiration is when water vapor comes from liquid water excreted by plants. Plants 'breathe' by exchanging carbon dioxide for oxygen through small openings in their leaves called stomata during photosynthesis.
