Subtract the second equation from the 1st equation
To get their combined time, get the sum of Vega's time and Janice's
![27.98\text{ sec}+25.679\text{ sec }=53.659\text{ sec}](https://tex.z-dn.net/?f=27.98%5Ctext%7B%20sec%7D%2B25.679%5Ctext%7B%20sec%20%7D%3D53.659%5Ctext%7B%20sec%7D)
Therefore, their combined time for their part of the relay is 53.659 seconds.
Subtract the 5x to get
3y=-5x+7
Then divide the whole equation by 3 to finally get
Y=-5/3x+ 7/3
Answer:
10-3x
Step-by-step explanation:
let the number=x
thrice the number becomes 3x
Assuming larger number = x,
smaller number = y,
x = 2y - 3
![2y - 3 + y = 69 \\ 3y = 72 \\ y = 24](https://tex.z-dn.net/?f=2y%20-%203%20%2B%20y%20%3D%2069%20%5C%5C%203y%20%3D%2072%20%5C%5C%20y%20%3D%2024)
![x = 2(24) - 3 \\ x = 45](https://tex.z-dn.net/?f=x%20%3D%202%2824%29%20-%203%20%5C%5C%20x%20%3D%2045)
Larger number = 45, smaller number = 24
Hope this helps. - M
