If you want a quicker answer on that, use photo math. If you take pictures of all of those individually, youll get your answer. Apologize for not giving an answer to your problem but i figured id let you know because its faster then coming on here and asking.
Answer:
Distance to grandparents' house
Step-by-step explanation:
distance = speed x time
time = distance/speed
y=60/x
y is time
x is speed
time = 60/speed
so 60 is distance to grandparents' house
Answer:
Yeah
Step-by-step explanation:
Answer:
The proof contains a simple direct proof, wrapped inside the unnecessary logical packaging of a proof by contradiction framework.
Step-by-step explanation:
The proof is rigourous and well written, so we discard the second answer.
This is not a fake proof by contradiction: it does not have any logical fallacies (circular arguments) or additional assumptions, like, for example, the "proof" of "All the horses are the same color". It is factually correct, but it can be rewritten as a direct proof.
A meaningful proof by contradiction depends strongly on the assumption that the statement to prove is false. In this argument, we only this assumption once, thus it is innecessary. Other proofs by contradiction, like the proof of "The square root of 2 is irrational" or Euclid's proof of the infinitude of primes, develop a longer argument based on the new assumption, but this proof doesn't.
To rewrite this without the superfluous framework, erase the parts "Suppose that the statement is false" and "The fact that the statement is true contradicts the assumption that the statement is false. Thus, the assumption that the statement was false must have been false. Thus, the statement is true."
