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 does the variable d represent? What value of d makes the equation true? Explain your reasoning.

so, converting firstly the mixed fractions to improper fractions and then "adding".

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218

ya

the answer to 1/4x+5/3x-4=2-1/12x is x=3

hope this if needed hmu
