To solve for x in the equation 102.5(x−11.92)=71.6, you need to simplify and isolate x.
First, distribute the 102.5 on the left side:
102.5x - 102.5(11.92) = 71.6
Next, simplify and combine like terms:
102.5x - 1215.2 = 71.6
Now, isolate x by adding 1215.2 to both sides:
102.5x = 1286.8
Finally, divide both sides by 102.5 to solve for x:
x = 12.537
Rounded to 3 decimal places, the answer is 12.537.
So, the correct response is: 12.619

To solve for n in the equation 50.3(n+9.25)=−120.72, you need to simplify and isolate n.
First, distribute the 50.3 on the left side:
50.3n + 50.3(9.25) = -120.72
Next, simplify and combine like terms:
50.3n + 463.075 = -120.72
Now, isolate n by subtracting 463.075 from both sides:
50.3n = -583.795
Finally, divide both sides by 50.3 to solve for n:
n = -11.595
So, the correct response is: -11.595
