3x - 8 = 2x + 15
Add 8 to both sides
3x = 2x + 23
Subtract 2x from both sides
x = 23
Each sandwich is toasted for 2 minutes and it takes 3 seconds to flip it.
The first two sandwiches will be toasted in 2 minutes (toasting) and 6 seconds (flipping).
The two will then be switched which will take 10 seconds.
The next two will again take 2 minutes and 6 seconds.
The final sandwich will take 5 seconds to be placed.
The final sandwich will also take 2 minutes to toast and 3 seconds to flip.
Total time:
2 + 2 +2 = 6 minutes
6 + 10 + 6 + 3 = 25 seconds
Total time is 6 minutes and 25 seconds.
All of them or which one???
Answer:
The difference in elevation is 7,716 ft
Step-by-step explanation:
Let
y -----> the elevation of Mt Owens
x -----> the elevation of the bolo cavern
we know that
To find the difference in elevation between the bolo cavern and Mt Owens, subtract the elevation of the bolo cavern from the elevation of Mt Owens
we have
y=7,295 ft ----> is positive because is above sea level
x=-421 ft ----> is negative because is below sea level
therefore
y-x=7,295-(-421)=7,295+421=7,716 ft
