1:what do you think is the biggest threat to our environment and why. 2:how to you feel when you see someone throw litter on the street
3:have you ever told somebody not to pollute the environment. How did they react
4:What positive examples do you know of people caring for the environment.

I think the biggest threat to the environment and how much pollution we have and how much is in the air, because obviously we breathe oxygen,and that's what air is. when someone throws water on the street I feel like they're just causing a bigger problem for the environment,because it just adds more pollution to the Earth. I told someone not to litter and they're just picked up and threw it away they didn't really think it was a big deal. some of the appositive examples I know our recycling, reusing, and using less plastic materials.

in the spreadsheet, click on a cell, then type the numbers or text you want and press enter or tab. to write data to a new line within a cell, press alt + enter. to enter the same data in several cells at the same time you must select the cells in which you want to enter the same data, in the active cell write the data and press ctrl + enter.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
