Answer:
w = -7z/2
Step-by-step explanation:
Our goal is to isolate w
1. subtract 3w from both sides to get 2w+9z = 2z
2. Subtract 9z from both sides to get 2w = -7z
3. Divide both sides by 2 to get w = -7z/2
We cannot simplify further, so this is our answer.
7.3 km/y
at least if i did this correctly but that's always a stretch.
because it takes 50 days to complete a km
so 365/50 = 7.3
