Twelve marbles are in a
row. One third of them are yellow. There are an
equal amount of red and blue. There are two less
green marbles than yellow. Explain how to find out
how many of each color of marble are in the row. pls answer I'll make brainliest! and due tomorrow. also please explain

yellow = 4

green = 2

blue = 3

red = 3

Explanation:

y = yellow marbles

r = red marbles

b = blue marbles

g = green marbles

y + r + b + g = 12

y = 1/3 (12) = 4

r = b

g = y - 2 = 4 - 2 = 2

That means...

4 + r + b + 2 = 12

Combine like terms

r + b + 6 = 12

Subtract 6

r + b = 6

Because r = b, plug in b for r

b + b = 6

2b = 6

b = 3

Which makes r = 3

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
