Use a vertical number line to think about how to represent the situation below. Then, answer the question.

A diver is 4 meters below sea level. What integer represents the location of the diver?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
