Answer:
The two numbers are 476 and 284
Step-by-step explanation:
Given:
He used an even number of blocks
The number of blocks is between 700 and 800
The number of blocks is the sum of two
To Find :
Two number = ?
Solution:
The sum of an odd number and an even number id always odd. So 423 can be eliminated
So two numbers must be any of the 4 remaining options
Its also given that the number lies between 700 and 800. So the sum should be greater than 700 and lesser than 800
by trial and error method
352+476 = 828 ( greater than 700 but greater than 800, condition fails)
352+326 = 678 ( lesser than 700 but lesser than 800, condition fails)
352+284 = 636 ( lesser than 700 but lesser than 800, condition fails)
476+326 = 802 ( greater than 700 but greater than 800, condition fails)
476+284 = 760 ( greater than 700 and lesser than 800)
Answer:
The multiplicative inverse of y is .
Step-by-step explanation:
Multiplicative inverse implies a value that you would multiply with the given value so as to give 1.
Let the multiplicative inverse of y be represented by a, so that;
a x y = 1
ay = 1
divide both sides by y to have,
a =
Thus, the multiplicative inverse of y is .
This is applicable to any given value. Examples:
i. Given 2, the multiplicative inverse is .
⇒ 2 x = 1
ii. What is the multiplicative inverse of 5?
The required answer is .
