<span>If k=f(z) and z=f(x) what is x=</span>y
Answer:
27
Step-by-step explanation:
Let brother's age = x
Ben age = 2x
2x+x =81
3x =81
x =27

There are 12 coins in the bag. For the first case, the probability that a penny is selected from the bag is 5/12 because there are 5 pennies in the bag. Also, the next one is 3/11. Multiplying the probabilities,
(5/12)(3/11) = 8/121
Can you send a picture of it? Then maybe I can help you answer it.
In the two little boxes write thnumber 2 in both
