Answer:
x = -10
Step-by-step explanation:
We just have to translate the problem correctly
>8 times a number is the same
this tells me that
>as 30 less than 5 times the number.
Now set them equal to eachother
Now isolate the variable x
The equation to find percent error is
where actual is the value that actually came out (in this case, 11.5 km) and theoretical is the value that was supposed to come out (in this case, 10 km). Just plug in the numbers and simplify.
So, the true answer would be 15%. Apparently, the question you're asking takes 11.5 as the theoretical and the 10 as the actual (which I personally disagree with)
If you plugged in the numbers that way, the answer comes out to 13.04%. So, the correct answer for your answer choices is c. 13%
