Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.

12 b. Marisol has the highest score in English.
<span>Nope. A consistent system is either dependent (both equations represent the same line) or independent. So in an independent system, the lines intersect in exactly one point, which means there is exactly one solution. A dependent system has an infinite number of solutions. An inconsistent system has no solution, so no system of linear equations can have exactly two solutions.</span>
