Then use this data as a conversion factor.
If we want to transform miles to kilometers then our conversion factor should be:
Now we must multiply the number of miles by this factori and thus we obtain the equivalent in kilometers
Rachel = x . Heathe = x/2 + 3
x/2 + 3 = 4
x + 6 = 8
x = 2 years
Answer: Not sure if it needs to be rounded but if it doesn't then its x=3.7876 but if it needs to be rounded to the nearest tenth then its x=3.8
Step-by-step explanation:
