Answer:
Below.
Step-by-step explanation:
15y + 12x = 18
5y + 4x = 6
The second equations is the first times 3 so they are basically the same.
Infinite Solutions.
2x+ 3y= 12
-6y= 4x-24 Rearranging the second equation:
-4x - 6y = -24 Multiplying the first equation by 2:
4x + 6y = 24
- we see that the last equation is -1 * previous equation.
So there are infinite solutions.
11,400 seconds
You would take 3 hours to minutes which is 180 then add the following 10 minutes and convert it to seconds.
It would depend on how large the rectangle is
3 multiplied by ten to the second power
