Answer:n=0.3168
Step-by-step explanation:
It looks to be 29, if the rule is to add 3z
Answer:
9 + f = 16
Step-by-step explanation:
So just say 9 + f = 16 since the tree grew to 16, and the f is the amount.
Using the first equation:
4x = y + 3 ---> y = 4x - 3
We then substitute this into the second equation:
7x - 9(4x-3) = -2 ---> 7x - 9x + 27 = -2 ---> -2x = -29 ---> x = 14.5
