Felicia is 9 years old. Her neighbor Katie is 10 years old. How much older is Katie than Felicia?

1 year

Step-by-step explanation:

Subtract 9 from 10 to get your answer, please thank me ðŸ™‚

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!

Step-by-step explanation:

older person's age - younger person's age = age difference

10 - 9 = 1

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
