Answer:
The given expression is divisible by 3 for all natural values of x.
Step-by-step explanation:
The given expression is
For x=1,
9 is divisible by 3. So, the given statement is true for x=1.
Assumed that the given statement is true for n=k.
This expression is divisible by 3. So,
.... (1)
For x=k+1
Using equation (1), we get
This expression is also divisible by 3.
Therefore the given expression is divisible by 3 for all natural values of x.
The mixed number have to become a improper fraction and then you have to subtract like this.
so 7 7/8 you have to multiply 7 times 8 and then add it by 7 .
You do the same thing with the other mixed number 3 times 4 plus 1
So the first one is 63/8 - 13/4 =
first the 4 in the 13/8 have to become 8 . so you do 4 times 2 = 8 and multiply the 13 by 2 = 26 .
so equal
63/8 - 26/8 = then you have to do 63 - 26 = 37 so is 37/8 and then simplify or divide .
when you divide you suppose to get 4 5/8
Answer:
the answers are 12.5, 5, 2, 0.8 and 0.32
Step-by-step explanation:
2(0.4)^-2
=2(6.25)
= 12.5
2(0.4)^-1
= 2(2.5)
=5
2(0.4)^0
=2(1)
=2
2(0.4)^1
=2(0.4)
=0.8
2(0.4)^2
=2(0.16)
=0.32
