Explanation
Let's first graph the elements:
Using the distance formula we get:

Solve 180=10x+10 to find your answer (:
21 because you can do 84 divided by 21 or you can also do 4 times any number that sounds like it would =84. (Stick with option 1 unless you are super confused)
Answer:
105 points.
Step-by-step explanation:
The scores of team A and B is 16 and 21.
if 16 = 80, The ratio of 16 to 21 is 5.
So, that means 16 x 5 is 80.
How many points did team B get?
score x gap between 16 to 21
= 21 x 5 = 105.
the team B got 105 points.
