plz answer fast it's emregency​

Answer 1

Step-by-step explanation:

Given :-

The numbers in the form of 7k+3

To find :-

Write the possible remainders when they are divided by 21?

Solution :-

Given that

The numbers are in the form = 7k+3

If they are divided by 21 then they must be greater than or equal to 21

that is k must be greater than or equal to 3

k≥3

If k = 3 then 7(3)+3 = 21+3 = 24

24/21 = 3 is the remainder

If k = 4 then 7(4)+3 = 28+3 = 31

=> 21+7+3

=> 21+10

The remainder = 10

So ,the numbers will be 24,31,38,...

The remainders are 3,10,17,...

Answer:-

The possible remainders for the given problem are 3,10,17,...
