Suppose b is any integer. If b mod 12 = 7, what is 8b mod 12? In other words, if division of b by 12 gives a remainder of 7, wha
vladimir2022 [97]

Answer:

Remainder = 8

Step-by-step explanation:

1. b mod 12 = 7

Add 12 to 7

b = 7 + 12 = 19

b = 19

So, 19/12 = 1 remainder 7

The remainder when 8b mod 12 = 8b/12

= (8*19)/12 = 152/12

= 12 remainder 8

Testing with a different value of b

2. b mod 12 = 7

Add 24 (12*2) to 7

b = 7 + 24 = 31

b = 31

So, 31 mod 12 i.e., 31/12 = 2 remainder 7

The remainder when 8b mod 12 = 8b/12

= (8*31)/12 = 248/12

= 12 remainder 8 again

So, no matter the starting value of b that was obtained, 8b mod 12 will always have a remainder of 8.
