Let the two ages be j and m, respectively. Then j+m>32.
Solving for Mary's age, we get m > 32 - j. Because j = m + 2, m > 32 - (m+2).
Continue solving for m: Adding m to both sides of this inequality results in
2m > 32 - 2. Then 2m > 30, and m > 15. Mary's age is greater than 15.
Answer:
![W\leq 6.4\ m](https://tex.z-dn.net/?f=W%5Cleq%206.4%5C%20m)
Step-by-step explanation:
we know that
The perimeter of a rectangle is equal to
![P=2(L+W)](https://tex.z-dn.net/?f=P%3D2%28L%2BW%29)
we know that
![L=7.6\ m](https://tex.z-dn.net/?f=L%3D7.6%5C%20m)
![P\leq28\ m](https://tex.z-dn.net/?f=P%5Cleq28%5C%20m)
substitute
![2(7.6+W)\leq28](https://tex.z-dn.net/?f=2%287.6%2BW%29%5Cleq28)
solve for W
![(7.6+W)\leq14](https://tex.z-dn.net/?f=%287.6%2BW%29%5Cleq14)
![W\leq14-7.6](https://tex.z-dn.net/?f=W%5Cleq14-7.6)
![W\leq 6.4\ m](https://tex.z-dn.net/?f=W%5Cleq%206.4%5C%20m)
