Answer:
The Gold team has 8 swimmers and the silver team also has 8 swimmers.
Step-by-step explanation:
Let T be the total number of swimmers on the Gold team. Since, the Gold team has a 2:3 ratio of 11 year olds to 12 year olds, the number of 11 year old is T' = 2/(2 + 3) × T = 2T/5 and the number of 12 year olds is T" = 3/(2 + 3) × T = 3T/5.
The silver team has a 3:8 ratio of 11 year olds to the total swimmers. Let T₁ be the number of 11 year old swimmers in the silver team. So, from the ratio 3:8, the number of 11 year old swimmers in the silver team is 3 and the total number of swimmers in the silver team is 8.
Since the number of 11 year old swimmers in both teams are the same, then
2T/5 = 3
T = 3 × 5 ÷ 2
T = 15/2
T = 7.5
T≅ 8
So, the Gold team also has 8 swimmers.
So, the Gold team has 8 swimmers and the silver team also has 8 swimmers.
Answer is y= 1/2x+1
One method is first substituting x=4,y=3 and next once again substituting x=y=2

Here is your answer:
There are two ways you can solve this equation:
1. You could round each decimal then divide:
16.8 --> 17 & 4.96 --> 5
"17 ÷ 5 = 3.4"
2. You could just divide:
"16.8 ÷ 4.96 = 3.38"
(Remember depending on the way you have to solve it would determine your answer.)
Hope this helps!
