Triple one number added to another number is 22. If the second number is
equal to 8 less than 2 times the first
number, find the two numbers.
First complete the equations below,
where x stands for the first number and y
stands for the second number.
3x + y = [?]; y = [ ]x-[]

Imagine a new pasture with grass growing on it. every day after the seeds have germinated, the number of blades of grass in the pasture triples. after 18 days, the entire pasture is completely covered in grass. how many days did it take for the pasture to be one-third covered in grass?
