The function r is defined over the set {integers from 40 to 50 inclusive}as r:x-- "the remainder when x is divided by 7" State the value of
1. r(47)

2. x for which r(x)=3

3. x which have zero as their solution

The function r is defined over the set {integers from 40 to 50 inclusive}as r:x-- "the remainder when x is divided by 7" State the value of
1. r(47)
Remainder of 47 / 7 is 5


2. x for which r(x)=3
Remainder of 45 / 7 is 3


3. x which have zero as their solution
Remainder of 42/7 and 49/7 both are zero

Thanks for your help. I appreciate it.
