Answer:
16
Step-by-step explanation:
Given that :
r + 9 = 4 greater Than s
r - 1 1 is how much less than s
r + 9 = s + 4
Solve for r
Subtract 9 from both sides
r + 9 - 9 = s + 4 - 9
r = s - 5
Hence,
r - 11 = (s - 5) - 11
r - 11 = s - 5 - 11
r - 11 = s - 16
r - 11 = s - 16
Therefore, r - 11 is 16 less than s
