16. If y varies directly as x, and x = 9 when y = 15, find y when x = 33?​
inna [77]

Answer:

y=55 when x is 33

Step-by-step explanation:

Use the direct variation formula:

\frac{y}{x} =k  or \frac{y}{x} =\frac{y}{x}

Insert the given values:

\frac{15}{9}=\frac{y}{33}

To simplify the equation, cross multiply:

15(33)=9(y)\\\\495=9y

Isolate the variable. Divide both sides by 9:

\frac{495}{9} =\frac{9y}{9} \\\\55=y

Therefore, when x is 33, y is 55.

:Done

A student writes "the quotient of 5 and x" to describe the algebraic expression -
pashok25 [27]

For this case we have to:

\frac {a} {b} = c

Where:

a: It's the Dividend

b: It is the Divider

c: Is the Quotient

Thus, the expression "the quotient of 5 and x" can be represented as:

\frac {5} {x} = y

Where "y" is the quotient of 5 and x.

ANswer:

\frac {5} {x} = y
