also : A football team lost 6 yards on first down, 8 yards on second down, and 7 yards on third down. How many total yards have they lost?
Answered by GPT 3.5
The result of adding 18 and -27 is -9.
Answered by GPT 3.5
The altitude at the surface of the water would be -42 meters + 20 meters = -22 meters.

Apologies for the confusion earlier. The correct calculation would be:

The whale's initial altitude is -42 meters, and it ascends 20 meters to the surface.

Therefore, the altitude at the surface of the water would be -42 meters + 20 meters = -22 meters.

So, the whale is at an altitude of -22 meters at the surface of the water.

To find the total yards lost by the football team, you need to add up the yards lost on each down.

On first down, they lost 6 yards.
On second down, they lost 8 yards.
On third down, they lost 7 yards.

To find the total yards lost, you would add these values together:

6 yards + 8 yards + 7 yards = 21 yards

Therefore, the football team has lost a total of 21 yards.
