To solve for x in the equation 102.5(x−11.92)=71.6, we can start by multiplying both sides of the equation by the reciprocal of 102.5, which is 1/102.5:
(x - 11.92) = (71.6 / 102.5)
Now, we can add 11.92 to both sides of the equation:
x = (71.6 / 102.5) + 11.92
Evaluating this expression, we find that x is approximately 12.618 when rounded to 3 decimal places. Therefore, the correct option is:
12.618

To solve for n in the equation 50.3(n+9.25)=−120.72, we can start by dividing both sides of the equation by 50.3:
(n+9.25) = -120.72 / 50.3
Next, we can subtract 9.25 from both sides of the equation:
n = (-120.72 / 50.3) - 9.25
Evaluating this expression, we find that n is approximately -6.85.
Therefore, the correct option is:
-6.85
