He rides 9 kilometers per hour.
Divide the total by the amount of kilometers that he rides.

Answer:
n = 0
Step-by-step explanation:
To solve this equation, we would have to get it into the form n = _. That would be our answer.
56n + 36n = 0
Combine like terms. 56n + 36n turns into 92n.
92n = 0
Divide both sides by 92 to get rid of the coefficient of 92 on the left side. On the right side, 0 divided by 92 is still 0.
n = 0
The solution to the equation would be n = 0.

Answer:
B
Step-by-step explanation:
From what we have here;
if a implies b and b implies c
It simply means that we have a implying c
the correct representation here is given in the second option
And thus, we have it that;
a => c
5x+(-20)=-15x and there you have it
Answer:
7. yes, because the angles are 180 degrees
8. CD=31 because CD=2(CP)=2(15.5)
9. No, because they both form an OBTUSE angle, not a straight angle nor a right angle
