Explanation:
1. The given expression is,
![A=lw](https://img.qammunity.org/qa-images/2022/formulas/mathematics/high-school/42dywiy9023rb2my23vr7n.png)
We need to solve it for w.
![w=(A)/(l)](https://img.qammunity.org/qa-images/2022/formulas/mathematics/high-school/fgkao73tp1fj79awgvzk4k.png)
2. The given expression is,
![C=\pi D](https://img.qammunity.org/qa-images/2022/formulas/mathematics/high-school/k8xfacaqa33z409wchwzdr.png)
We need to solve it for D.
![D=(C)/(\pi)](https://img.qammunity.org/qa-images/2022/formulas/mathematics/college/fksbaqqg5fbqodb2mf3cja.png)
3. The given expression is,
![v=s+gt](https://img.qammunity.org/qa-images/2022/formulas/mathematics/college/dvlc1mg8p5tba7hqbj9ore.png)
We need to solve it for s.

4. The given expression is,
![5x-2y=11](https://img.qammunity.org/qa-images/2022/formulas/mathematics/college/xsdtdqdszzozz1fog47lhs.png)
We need to solve it for y.
![D=(5x-11)/(2)](https://img.qammunity.org/qa-images/2022/formulas/mathematics/college/msj5u3w6snz2yl6sex0za9.png)
5. The given expression is,
![P_1V_1=P_2V_2](https://img.qammunity.org/qa-images/2022/formulas/physics/college/bqg1yd0tt602ajtelgxdaz.png)
We need to solve it for P₂. So,
![P_2=(P_1V1)/(V_2)](https://img.qammunity.org/qa-images/2022/formulas/mathematics/college/unve24zklwm7l7l9j2tic6.png)
