Ascuba diver dove 18 ft below the
surface to observe a school of fish.
then he dove another 24 ft to the
bottom. if he started at sea level.
what was his elevation when he
reached the bottom?

Hello!

Let's start from the very beginning. He starts at sea level. This would make his elevation 0 feet.

Then, he dives 18 feet downwards. This would decrease his elevation by 18 feet, making it 18 feet below sea level.

Finally, he dives 24 feet downwards. This would decrease his elevation by another 24 feet. 24 feet below 18 feet below sea level would be 42 feet below sea level, as -18 - 24 = -42.

Therefore, your final answer is 42 feet below sea level.

Hope this helps!

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

c is the answer
