Answer:
here 1st case
x+y=77
or,x=77-y
second case
4x+2y=286 (according to question)
putting value of x from first case
4 (77-y)+2y=286
or,308-4y+2y=286
or,308-286=2y
or,22=2y
or,11=y and x=77-11
x=66
Step-by-step explanation:
so,y=11 and x=66
It could be either.
1 + 1 + 1 = 3, which is prime
2 + 2 + 2 = 6, which is composite
Step-by-step explanation:
We will prove by mathematical induction that, for every natural ,
We will prove our base case, when n=4, to be true.
Base case:
Inductive hypothesis:
Given a natural ,
Now, we will assume the induction hypothesis and then use this assumption, involving n, to prove the statement for n + 1.
Inductive step:
With this we have proved our statement to be true for n+1.
In conlusion, for every natural .
