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 the canoe's is -4.8 meters. The equation 12 + d = -4.8 represents this situation.

What is the value of the variable in this equation?

Answer 1

7.2 because you just add the -4.8 to cancel out the -4.8 on the right side. and you get 7.2

Answer 2

The distance between the ballon and canoe is 16.8 meters. So -12+d=4.8
