This the problem we are looking at: 6 pounds/18 = 72 ounces /?
To solve this, we have to make the unit of measurement the same. There are 16 ounces in 1 pound. So, there are 72 ounces in 4.5. To find that you just do 72 divided by 16. This is the new problem we are looking at: 6 pounds/18 = 4.5 pounds/?
To find ?, you must divided 6 divided by 4.5 to find the difference between the two to keep the same rate. That equals 1.33333333.
What is done to the numerator, you must do to the denominator to keep the same rate so now you divide 18 divided by 1.33333333 which equals 13.5
So for 72 ounces (4.5 pounds) it will cost $13.50
I hope this helps:)
Answer:
4x(x^4-7)
Step-by-step explanation:
Answer:
(a) (x times x) + (5 times x) + 4
Step-by-step explanation:
Using my answer you first do exponent, so x times x then 5 times x and then 4 times x BUT keep those numbers apart still!
okay now we will take 
and add that value to 4 so we now have the numerator‘s value and for the denominator you will take And multiply 4 times x and add those two answers and finally add the 3 you will have finished the denominator and FINALLY divide the numerator‘s result by the denominato’s result and you now have your answer.
the secret? Order of Operations or PEMDAS
1. Parentheses
2. Exponents
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
5. BOOM the result will be your answer!
Simplified is 18/25. thats the answer
