Answer:
1, 4, 3, 6, 2, 7, 5
Step-by-step explanation:
The circle operator in
means that the function named on the left (f) operates on the result of the function named on the right (g). So, the notation

means

That is, g(x) is computed and used as input to the function f. When the function definitions are as shown, the evaluation proceeds in these steps.

If your step choices at the bottom are numbered 1 to 7 left-to right, then the sequence is as shown in the Answer section above.
Answer:
B
Step-by-step explanation:

Answer:
2/12
Step-by-step explanation:
4w=2/3
1/4(4w)=1/4 x 2/3
w=2/12
Let x be your first alloy
2/5x+7/10(30-x)=1/2(30)
4x+210-7x=150
3x=60
x=20
So, you need 20 lbs of the first alloy, and 10 parts of the second to make 30 lbs of half iron and half silver alloy!
2(10+5)−5
=(2)(15)−5
=30−5
=25
C is the answer.
