Answer:
1.5 cm.
Step-by-step explanation:
If 1 cm = 30 km, then half a cm equals 15 km.
We need to find 45 km. We know that 1 cm = 30km and half a cm = 15 km. Adding both of these together, we can get 1.5cm = 45km.
just move the 15 the left and divide 5 and u should get c=3
The answer is v= -12.
Hope this helps
