To solve for x in the equation 102.5(x−11.92)=71.6, we can follow these steps:
First, distribute 102.5 to the terms in the parentheses:
102.5x - 102.5(11.92) = 71.6
Next, simplify the equation by multiplying:
102.5x - 1218.4 = 71.6
Now, isolate the term with x by adding 1218.4 to both sides:
102.5x = 1290
Finally, solve for x by dividing both sides by 102.5:
x = 1290 / 102.5
x ≈ 12.585 (rounded to 3 decimal places)
Therefore, the correct answer is 12.585.
First, distribute 102.5 to the terms in the parentheses:
102.5x - 102.5(11.92) = 71.6
Next, simplify the equation by multiplying:
102.5x - 1218.4 = 71.6
Now, isolate the term with x by adding 1218.4 to both sides:
102.5x = 1290
Finally, solve for x by dividing both sides by 102.5:
x = 1290 / 102.5
x ≈ 12.585 (rounded to 3 decimal places)
Therefore, the correct answer is 12.585.

To solve for n in the equation 50.3(n+9.25)=−120.72, we can follow these steps:
First, distribute 50.3 to the terms in the parentheses:
50.3n + 50.3(9.25) = -120.72
Simplify the equation by multiplying:
50.3n + 462.275 = -120.72
Next, isolate the term with n by subtracting 462.275 from both sides:
50.3n = -120.72 - 462.275
50.3n = -582.995
Finally, solve for n by dividing both sides by 50.3:
n = -582.995 / 50.3
n ≈ -11.597 (rounded to 3 decimal places)
Therefore, the correct answer is -11.597.
First, distribute 50.3 to the terms in the parentheses:
50.3n + 50.3(9.25) = -120.72
Simplify the equation by multiplying:
50.3n + 462.275 = -120.72
Next, isolate the term with n by subtracting 462.275 from both sides:
50.3n = -120.72 - 462.275
50.3n = -582.995
Finally, solve for n by dividing both sides by 50.3:
n = -582.995 / 50.3
n ≈ -11.597 (rounded to 3 decimal places)
Therefore, the correct answer is -11.597.
