Answer:
6/25
Step-by-step explanation:
Because england, scotland and france are european team and they make up 3/5 of all the teams, you multiply 3/5 by 2/5 because the south american teams are brazil and argentina which make up 2/5 of the total teams.

Answer:
-0.5
Step-by-step explanation:
Answer:
53
Step-by-step explanation:
they are a linear pair so x + 2x + 21 = 180 so you subtract 21 from both sides, combine x and 2x then divide by 3 to get 53
For this case we have the following equation:
From here, we must clear the value of x.
For this, we follow the following steps:
1) Place the variable on one side of the equation and the constant on the other side of the equation:
2) Make common factor x:
3) Clear the value of x:
Answer:
The relationship between x and the difference of a - b is inversely proportional.
