Hope this helps.
([x]12+ [y]12) = f([x+y}12) = [x+y]4 = [x}4+ [y]4 = f([x]12)+ f([y]12)
Answer:
The answer is b. But you asked for the thought process so...
Step-by-step explanation:
Let speed of the 1st trip x miles / hr. and speed of the 2nd trip 3x / hr.
We know that
Speed = Distance/Time.
Or, Time = Distance/Speed.
So, the time taken to cover a distance of 50 miles on his first trip = 50/x hr.
And the time taken to cover a distance of 300 miles on his later trip = 300/3x hr.
= 100/x hr.
So we can clearly see that his new time compared with the old time was: twice as much.
Have a great day :)
Answer:
Well you can either straight up subtract from the total degrees of a triangle using the sum of both of the given angles, which would equal x, or you can make an equation. I’ll do both.
180-78-51=51, x=51
78+51+x=180
129+x=180
x=180-129
x=51
