Mary is 15 years older then her niece katie. in 10 years mary is two times as old as katie. how old are mary and katie now?

i dont know if you cant find a way its best to actually add all of them start from 105 tho

step-by-step explanation:

since we know that the two functions are equal, f (x) = g

(x), therefore when we equate the two equations the result should be similar to

3x = x – 4:

a. f(x) = 3x, g(x) = x – 4

equating the two functions:

3x = x – 4             (correct)

so we now got our answer (a)
