Answer:

  -16.8

Step-by-step explanation:

The equation can be solved by performing the inverse of the operation that is done to the variable. Here, 12 is added to the variable. The inverse of that operation is addition of the "additive inverse", or "opposite" of 12:

  12 + d = -4.8 . . . . . . given equation

  12 -12 +d = -4.8 -12 . . . . . the same operation is done to both sides

  d = -16.8

The value of d that makes the equation true is -16.8.

_____

The addition (subtraction) property of equality tells you that adding (subtracting) the same number from both sides of an equation will not change the value of the variable.

allsm [11]
Knowing that pluto is travelling at 10,604 and the Earth travels 6.28 times faster; 

6.28x=10,604 mph (where x is the speed of the earth) 
x=10,604/6.28 
x=1688.53 mph for the Earth 

Double check by multiplying the answer found by 6.28 to see if it gives pluto's speed. 

1688.53×6.28=10, 604 mph 

Therefore, our solution is correct. 

Hope I helped :)
