Answer:

Step-by-step explanation:
So we have the two functions:

And we want to find g(f(3)).
So, let's find f(3) first:

Multiply:

Subtract:

Therefore, we can substitute -1 for f(3):

Now, find g(-1):

Multiply:

Add:

And we're done!
So:

Hello!

We can go through each answer to verify whether each is equivalent to 8 : 6.
4 : 3 is equivalent to 8 : 6 because reducing the ratio 8 : 6 by a factor of 2 yields 4 : 3.
6 : 8 is not equivalent to 8 : 6 because the ratio is reversed.
16 : 12 is equivalent to 8 : 6 because the ratio is increased by a factor of 2.
10 : 8 is not equivalent to 8 : 6. We can verify this by checking whether each term was scaled equally:
10 ÷ 8 = 1.25
8 ÷ 6 = 1.33. Therefore, they are unequal.
7 : 5 is not equal to 8 : 6 for the same reason.
The only correct choices are:
4 : 3 and 16 : 12.
Answer:
720 apples
Step-by-step explanation:
Let A be the number of apples in the small pack.
QTY for Small Cartons is 15A,
QTY for Big Cartons is 20(A+15) = 20A+300
From small cartons makes 25% or 1/4 of total, means the big carton makes 75% of total, or 3/4 of total. This also means the qty in big carton is 3 times of small carton
20A+300 = 3X (15A)= 45A
300 = 25A
A=12
Altogether = 15A+(20A+300) = 720 Apples
You would use 72/9 , ( division ).
