Answer:
There are 10 teams.
Step-by-step explanation:
Given that the question wants at least 48 swimmers so any numbers above 47 are counted.
In this diagram, there are 10 teams consisting 48 swimmers and above, 48, 52, 53, 63, 76, 79, 82, 84, 85 and 86.
Equation 1:
b+h=34
Equation 2:
h-b=8
OR
b-h=8
* since we did not know whether b>h or h>b
Let's assume h>b, so we use h-b=8
(b+h)-(h-b)=34-8
b+h-h+b=26
2b=26
b=13
Then, substitute b=13 into the equation
h-b=8
h-13=8
h=21
If we use b-h=8, we will get b=21, h=13
Answer:
b=13,h=21 OR
b=21,h=13
All you do is 104 times 50 and then you get your anwser
