Answer: 8 weeks
explanation: 125 + 15x = 245
You then have to subtract 125 from both sides so we can isolate our variable which will give us 15x = 120 . Divide 15 from both sides : 15x/15 = 120/15 which will give us x = 8.
For the units positions of all numbers we have:
![z+7+5=4 \\ z+12=4](https://tex.z-dn.net/?f=z%2B7%2B5%3D4%20%5C%5C%20z%2B12%3D4)
From this we can conclude that total sum of these three numbers is 14. Number 1 we carry to next step. So we have:
![z+12=14 \\ z=2](https://tex.z-dn.net/?f=z%2B12%3D14%20%5C%5C%20z%3D2)
For the tens positions of all numbers we have:
![4+2+x+1=1 \\ 7+x=1](https://tex.z-dn.net/?f=4%2B2%2Bx%2B1%3D1%20%5C%5C%207%2Bx%3D1)
The extra number 1 on left side comes from the carry from last step. Similar to ones position we know that total sum is 11.
![7+x=11 \\ x=4](https://tex.z-dn.net/?f=7%2Bx%3D11%20%5C%5C%20x%3D4)
Now we insert x and z to find out y:
![42+27+45=y14 \\ 114=y14 \\ y=1](https://tex.z-dn.net/?f=42%2B27%2B45%3Dy14%20%5C%5C%20114%3Dy14%20%5C%5C%20y%3D1)
Now we need to find out the product of these three numbers:
Answer:
41.79%
Step-by-step explanation:
To be on the swim team, we look at the right most (total) number int he table of "on the swim team" row. That is 28.
The grand total is the bottom-rightmost. That is 67.
Hence, probability of being on swim team is 28/67 = 41.79%
