Question

A balloon is floating above a lake and a sunken canoe is below the surface of the lake. The balloon's vertical position is 12 meters and conoe's is -4.8 meters. The equation 12+d=-4.8 represents this situation. A) what does the variable d represent?

Answer 1

Answer:

The answer is -16.8

Step-by-step explanation:

The equation is 12+d=-4.8 so what we need to do is the following:

12+d-12=-4.8-12 subtract 12 from both sides.

and we get an answer of d = -16.8

Answer 2

d means the position of the canoe with respect to the balloon.

Given that the balloon's vertical position is 12 meters and conoe's is -4.8 meters.

It means upward direction is positive. So balloon is 12 meters upwards from the water surface.

And the sunken canoe is 4.8 meters below the water surface.

The distance between them is 12 - (-4.8) = 12 + 4.8 = 16.8.

from the given equation: 12+d = -4.8

or, d = -4.8 - 12

or, d = -16.8

This is same as the distance but has a negative sign.

So d means the position of the canoe with respect to the balloon.
