Answer: The answer is 5x+6

Step-by-step explanation:

1/3(9x+16+2)+2x

= 1/3(9x)+1/3(16)+1/3(2)+2x

=3x/1+16/3+2/3+2x/1

=3x/1+2x/1+16/3+2/3

Take the L.C.M

=3x+2x/1+16+2/3

=5x/1+18/3

=5x+6

Suppose that y varies inversely as x and that y=8 when x=3. Calculate the value of y when x= 10.
Svetach [21]

\bf \qquad \qquad \textit{inverse proportional variation} \\\\ \textit{\underline{y} varies inversely with \underline{x}} ~\hspace{6em} \stackrel{\textit{constant of variation}}{y=\cfrac{\stackrel{\downarrow }{k}}{x}~\hfill } \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \textit{we know that } \begin{cases} y = 8\\ x = 3 \end{cases}\implies 8=\cfrac{k}{3}\implies 24=k~\hfill \boxed{y = \cfrac{24}{x}} \\\\\\ \textit{when x = 10, what is \underline{y}?}\qquad \qquad y = \cfrac{24}{10}\implies y = \cfrac{12}{5}

Find tan A. Can someone help me with this one??
marta [7]

Answer:

tan A = 5/12

Step-by-step explanation:

To find tangent of a triangle, it is this ratio : opposite / adjacent.

Knowing that "A" is the given angle, 5 is the opposite and 12 is the side adjacent to "A". Putting these values together, the tangent is

5 (opposite)/12 (adjacent).

Hope this helps!

Which expression is equivalent to 4 square root 6 divided by 3 root 2?
saw5 [17]

Answer:

\sqrt[12]{55296}/2

Step-by-step explanation:

\sqrt[4]{6}/\sqrt[3]{2}=1.2422

\sqrt[12]{27}/2=0.66 <-- not matching with the top expression.

\sqrt[4]{24}/2=1.11<--not matching with the top expression.

\sqrt[12]{55296}/2=1.2422<-- matches!!

\sqrt[12]{177147}/3=0.91<-- not matching with the top expression.
