Answer:
~q→~p
Step-by-step explanation:
The contrapositive of a statement is formed by negating the hypothesis and conclusion of a statement and switching them (the hypothesis becomes the conclusion and vice versa).
With this definition we can conclude that the contrapositive of p→q would be ~q→~p
For this case we have:
If after 2 hours the marathon runner has traveled 22 kilometers we have:
2h -----------> 22km
Applying a rule of three, we can know the time it takes to run 42km. So, we have:
2h -----------> 22km
x -------------> 42km
Where "x" is the time it takes to travel 42km. Resolving we have:




Thus, after 3.82 hours the marathon runner will travel 42km.
Answer:
3.82 hours
Answer:
y=-37
Step-by-step explanation:
0+6y=7(y+6)-5
0+6y=7y+42-5
6y=7y+37
-1y=37
y=-37
True because rational numbers are countable, but the irrational numbers are uncountable.
