Answer:
67 inches
Explanation:
Let's call the height of Louise 'L', the height of Miriam 'M' and the height of Jeffery 'J'.
Then, we can write the following equations and inequations:
![L \leq M - 1](https://img.qammunity.org/2021/formulas/mathematics/college/vl58nf5odsygzby8qzlddurnmb0u2nb6s9.png)
![L \geq J + 2](https://img.qammunity.org/2021/formulas/mathematics/college/aqjwhtzizie9qb5l0x7y5xc8ja8kzp87lo.png)
![J = 64](https://img.qammunity.org/2021/formulas/mathematics/college/mj10yvj3dj2etjsxbvdodc04e8kmzg01up.png)
![M \leq J + 5](https://img.qammunity.org/2021/formulas/mathematics/college/uwah35ef96ugqvqywqktvlvkdboso0ld75.png)
Substituting J in the second and four inequations, we have:
![L \geq 66](https://img.qammunity.org/2021/formulas/mathematics/college/6amwx650utryu81h2wkfvn46nuats1wq4i.png)
![M \leq 69](https://img.qammunity.org/2021/formulas/mathematics/college/wug4sbcun4k8wo5c4bmovh13qmxry2rtak.png)
If we assume the maximum value for M, in the first inequation we have that:
![L \leq 68](https://img.qammunity.org/2021/formulas/mathematics/college/insxkpdwc2lmf5v9eu6nnqsfwa5p93rwmd.png)
So the height of Uncle Louise is greater than or equal 66, and lesser than or equal 68, so his height could be 67 inches for example.
