This question is impossible to solve.
this is why:
if 4x-4=0
then x=1
so if 8x + 4 = 8
then x is false.
I get these question quite a lot in my GCSEs.
you have to prove why they are fake.
Answer:
A multiple choice question with 6 options will have a 16.7% chance of getting the answer correct, and a ratio of 1:6.
Step-by-step explanation:
You have a 1 in 6 chance of getting the answer correct, which can be represented with the fraction \frac{1}{6} .
To get a percentage, simply divide the 1 by the 6 and you will get an answer of 0.16666667. Multiply this by 100 and you have your answer.
To get a ratio, convert the fraction to a ratio making the left side of the ratio the numerator (the 1) and the right side the denominator (the 6).
