Answer:
first
Step-by-step explanation:
f(n) =56 (0.5)^(n-1)
f(1) = 56 (0.5)^0= 56*1 = 56
f(2) =56 (0.5)^1 = 56* 0.5 = 28
f(3) = 56 (0.5)^2 = 14
f(4) = 56 (0.5)^3 = 7
Answer:
(C) 18
Step-by-step explanation:
We can create a systems of equations. Assuming
is Michelle's age,
is Joan's age, and
is Ryan's age, the equations are:



We can use substitution, since we know the "values" of m and j.


So we know that Joan is 18 years old.
Hope this helped!
