Y = total amount of money spent
x = cost of one drink
So our expression is:
4x + 12.75
4x stands for 4 drinks times x price of one drink
The 12.75 is a one time fee for the pizza, since Kiyo isn't buying multiple pizzas.
The problem also asks us to find the total price, so we write an equation:

We insert what x is which in this case is $3

Order of Operations tells us to multiply first:

Now add your values:

Therefore, Kiyo spent a total amount of 24.75 at Paola's pizza.
Let's check our problem just in case:

Since we now know what y is equal to, we can plug that into our original equation and check just to verify
We should subtract 12. on both sides of the equation because of inverse operations:

We are left with:

We divide:

Our result is:

Which checks out because each drink was in fact, $3 dollars as stated in the word problem. Hope that was thorough enough.
Answer:
x = 7.3
Step-by-step explanation:
area = base × height / 2
21.9 = 6 × x / 2
43.8 = 6x
x = 7.3

Answer:
There will be 20 grams of fat in 10 pounds of chicken.
Step-by-step explanation:
Based of the pattern you can tell that the Grams of fat will always be double the amount of pounds.
2 grams of fat in 1 pound
9 grams in 4.5 pounds
So:
10 * 2 = Grams of fat
10 * 2 = 20 Grams of fat.
So there will be 20 grams of fat in 10 pounds of chicken.
