3000/100 = 30. When you go from Centimeters to Meters you divide by 100.
Answer:
the answer b or c I hold this helps
Ok, so we kno that
A + B = 90
we also know that
A - B = 20
There are a lot of ways to solve this, but I think elimination will be best
A + B = 90
+ (A - B = 20)
-----------------------
2A = 110
A = 55
Therefore,
B = 90 - 55 = 35
