Answer:
f=7/4
Step-by-step explanation:
substitute x for 4 and do the equation you will get the equation f(4)=1/2(4)+5 simplify to the equation to 4f=2+5. Then do the addition and get 4f=7. Divide both sides by 4 and get f=7/4
2 to the second power times 7 to the seventh power
It is a very simple answer but it works!
Answer:
OPTION C
Step-by-step explanation:
If SOLUTION A has 4 cups then SOLUTION B has 2. If SOLUTION A has 8 then SOLUTION B has 4.
Note that for every 2 cups of Solution A, we have 1 cup of Solution B.
So, OPTION A is incorrect.
If there are 4 cups of Solution A, then there are 4 + 2 cups in total.
That means the ratio of cups of SOLUTION A to the total number of cups is:
4 : 6 = 2 : 3
Similarly, 8 : 12 = 2 : 3
And, 12 : 18 = 2 : 3
And, 16 : 24 = 2 : 3
So, we see that the ratio is 2 : 3.
Therefore, OPTION C is the correct answer.
