A scuba diver dives to a depth of 50 feet, then rises 15 feet, sinks 12 feet, then rises 20 feet. Write an expression to describe this situation. Then solve it.

-50 + 15 - 12 + 20 = ?

-27

To write an expression to describe this situation, we can break it down step by step using positive and negative numbers to represent the depth changes.

Step 1: Dives to a depth of 50 feet (-50)
Step 2: Rises 15 feet (+15)
Step 3: Sinks 12 feet (-12)
Step 4: Rises 20 feet (+20)

Putting it all together, the expression would be:

-50 + 15 - 12 + 20

To solve this expression, you simply add and subtract the values:

-50 + 15 - 12 + 20 = -27

So, the scuba diver's final depth is -27 feet.

thank you!!

thank you

Plz help me with this question: A scuba diver dives at a rate of 20 feet per minute. What is the depth of the diver after 4 minutes?

@Amelia i had that same question
