Answer: ( -∞ , - 21 )
Step-by-step explanation:
Let the number be x , so from the question , we have
5(x+27) ≥ 6 ( x + 26 )
expanding , we have
5x + 135 ≥ 6x + 156
5x - 6x ≥ 156 - 135
- x ≥ 21
Therefore :
x ≤ - 21
So , the numbers less or equal to -21 are -21 ,-22 , -23 ...
so the solution set is ( - ∞ , 21 )
