Answer:
c. 15 and b. 9
Step-by-step explanation:
It's only 15 because 12+3 is 15. 15 is three steps away from 12 on a number line. The other one would be 9 because it is backwards three from 12 on a number line. 12-3 is 9. So your answers would be 15 and 9 (c and b)
The 3 units from 12 on a number line is 4units
