Answer:
![d \le -3](https://tex.z-dn.net/?f=d%20%5Cle%20-3)
Step-by-step explanation:
The given inequality is;
![\frac{d-3}{10} \ge \frac{2d+3}{5}+\frac{d+3}{3}](https://tex.z-dn.net/?f=%5Cfrac%7Bd-3%7D%7B10%7D%20%5Cge%20%5Cfrac%7B2d%2B3%7D%7B5%7D%2B%5Cfrac%7Bd%2B3%7D%7B3%7D)
Clear the fraction by multiply through by 30;
![3(d-3) \ge 6(2d+3)+10(d+3)](https://tex.z-dn.net/?f=3%28d-3%29%20%5Cge%206%282d%2B3%29%2B10%28d%2B3%29)
Expand;
![3d-9\ge 12d+18+10d+30](https://tex.z-dn.net/?f=3d-9%5Cge%2012d%2B18%2B10d%2B30)
Group like terms;
![3d-12d-10d \ge 18+30+9](https://tex.z-dn.net/?f=3d-12d-10d%20%5Cge%2018%2B30%2B9)
![-19d \ge 57](https://tex.z-dn.net/?f=-19d%20%5Cge%2057)
Divide through by -19 and reverse the sign.
![d \le -3](https://tex.z-dn.net/?f=d%20%5Cle%20-3)
