Students were requested to answer a question at schools and to assert what is most important for them to succeed. The one that response stood out from the rest was practice. Successful people definitely not born successful; they become successful via hard work and persistence. If you tend to accomplish your goals, keep this in mind! just below are one of the answer and question example that you might possibly benefit from to practice and develop your knowledge and also give you insights that might assist you to keep up your study in school.

## Question:

A scuba diver used the expression below to describe his position in relation to sea level.

2 + (–20) + 8

Which statement could describe the diver’s movements?

a.Starting on a platform 2 feet above sea level, dive down to a location that is 18

feet below sea level, and then rise 8 feet.

b.Starting on a platform 2 feet above sea level, dive down to a location that is 20 feet below sea level, and then rise 8 feet.

c.Starting 2 feet below sea level, dive down 20 more feet, and then rise to a location that is 8 feet below sea level.

d.Starting 2 feet below sea level, dive down 18 more feet, and then rise to a location that is 8 feet below sea level.

## Answer:

**Answer:**

a.Starting on a platform 2 feet above sea level, dive down to a location that is 18 feet below sea level, and then rise 8 feet.

**Step-by-step explanation:**

The first number (2) is positive and represents the height above the sea level that the scuba diver started. So, options c) and d) are incorrect.

If the (-20) represent

s the position (-20) feet below the sea, as stated in option b), then, the position (+8) will represent that the scuba diver will be 8 feet above the sea level in the next position, which has no sense.

Therefore, option a) is the correct one.

From the answer and question examples above, hopefully, they are able to guide the student handle the question they had been looking for and observe of all sorts of things declared in the answer above. You would probably then have a discussion with your classmate and continue the school learning by studying the topic collectively.
