B. 1/4(n - 64)
Multiplying n and -64 by 1/4 leaves you with 1/4n - 16, the original equation.
Answer:
D
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, thus
DE = BE , substitute values
4y - 8 = y + 10 ( subtract y from both sides )
3y - 8 = 10 ( add 8 to both sides )
3y = 18 ( divide both sides by 3 )
y = 6
Thus
BD = y + 10 + 4y - 8 = 5y + 2 = 5(6) + 2 = 30 + 2 = 32 → D
Count each as one and you should get your answer
Answer and Solution:
As per the question:
Given:
If
To prove:
Proof:
Suppose
As we know that:
Therefore,
or
Now, if we assume that
Then
Since,
and
But
A and B are disjoint set and
Therefore, this is contradictory.
Thus
So,
Every element in the set A is also present in the set C
Therefore,
Hence, proved.
