Answer:
D. 66/2
Step-by-step explanation:
If you are trying to figure out what operation to perform first, then follow PEMDAS.
<em>P: Parenthesis</em>
<em>E: Exponents</em>
<em>M: Multiplication</em>
<em>D: Division</em>
<em>A: Addition</em>
<em>S: Subtraction</em>
<em />
So first we start with what is in parenthesis. Since there are two operations within the parenthesis, we start with the division first since it comes first in PEMDAS. This is why D. 66/2 is our best answer.
30 percent were fish 10 percent were birds 10 percent were lizards
The f(9) = 1
first you plug in 9, where x is
f(9) = 2/3(9) - 5
multiply
f(9) = 6 - 5
subtract
and you should get f(9) = 1
