Answer: 
Step-by-step explanation:
According to the information given in the exercise, you know that the total amount of butter (in pounds) that were divided evenly, is:

The exercise explains that they filled six dishes with that division. Therefore, in order to calculate the value of the variable "x", you need to divide
by 6.
But first it is important to remember the Division of fractions:

Therefore, applying that rule, you get:

Finally, reducing the fraction you get the following result expressed as a fraction:

Answer:
400cm²

Answer:7.) C 8.) A
Step-by-step explanation:
Hello!
Judging on the questions you have provided I have come to the conclusion that to solve all of these you need to find the value of x by isolating it all on one side and simplifying.
For question #1 the first step would be to subtract 6 from each side.
The outcome should be -x=-6-12, and if simplified -x=-18.
Next, you want to divide each side by -1 because x needs to always be positive when finding the solution.
Your answer for #1 should be X=18, D.
For question #2 the first step you should take is to subtract 1.33 from each side to isolate x.
The outcome should be x=7.82-1.33, and if simplified x=6.49.
Thus your answer for #2 should be X=6.49, A.
For question #3 the first step you should take to approaching the equation is to isolate x by adding 15.99 towards each side of the equation.
The outcome should be x=58.06+15.99, and if simplified x=74.05.
Thus your answer for question #3 should be X=74.05, D.
Lastly, for question #4 the first step you should take towards isolating x is to divide the entire equation by 1.32.
Your outcome should be x= 6.8
Thus, your answer for the last question, #4, should be X=6.8, C.
Hope this helped!
