1/7+2x/3=(15x-3)/21  make all terms have a common denominator of 21

3+14x=15x-3  subtract 3 from both sides

14x=15x-6  subtract 15x from both sides

-x=-6 divide both sides by -1

x=6

*Notice the use of parentheses in this format to make it clear what the numerators and denominators are...

12-ounce bottle of orange juice contains 33 grams of sugar. Complete the table to determine the amount of sugar in different siz
svp [43]

A proportional relationship is a relationship between variables such that the amount of one variable is a multiple of the other variable

A table showing the amount of sugar in different sizes of orange juice is presented as follows;

\begin{array}{|c|cc|}\mathbf{Amount \ of \ orange \ juice, \ x}&&\mathbf{Quantity \ of \, sugar\ (g), \ f(x)}\\3&&8.25\\6&&16.5\\9&&24.75\\12&&33\\15&&41.25\end{array}\right]

Reason:

The given parameter are;

12 ounces of orange juice contains 33 grams of sugar

Therefore, we have;

The amount of sugar per ounce of orange juice is given as follows;

1 \ ounce \ of \ orange \ juice \ contains,  \dfrac{33 \ grams }{12 } = 2.75 \, grams \, of \, sugar

Therefore, there are 2.75 grams of sugar per ounce of orange juice

which gives;

The amount of sugar in different sizes of orange juice, f(x) = 2.75·x

Where <em>x</em> represents the amount of orange juice, and f(x) represents the amount of sugar in the orange juice

A table showing the amount of sugar present in different sizes of orange juice is given as follows;

\begin{array}{|c|cc|}\mathbf{Amount \ of \ orange \ juice, \ x}&&\mathbf{Quantity \ of \, sugar\ (g), \ f(x)}\\3&&8.25\\6&&16.5\\9&&24.75\\12&&33\\15&&41.25\end{array}\right]
