In a thoughtful paragraph or more, explain why you think some people judge each other on the basis of their skin color, religion, living situation, appearance, etc. Where does that come from? Why do some people do that? We know it's not right, but why does it happen sometimes?
We have encountered that in our book before this, and we are seeing more of it in what we are reading now.

many scientists' predictions of climate change include: warmer temperatures, rising sea levels, and more frequent storms.

that is the wrong

x=4, y=4

step-by-step explanation:

y=2x-4;

x+2y=12

we can use substitution since the first equation is solved for y

where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

distribute the 2

x+4x-8 = 12

combine like terms

5x-8=12

add 8 to each side

5x-8+8=12+8

5x=20

divide by 5

5x/5 = 20/5

x =4

we still need to solve for y

y = 2x-4

we know x =4

y = 2(4) -4

y = 8-4

y=4

greet them:

buenas noches.

that is considered night time which is when "good night" is used.
