ANSWER

The correct answer is

EXPLANATION

The expression given to us is,

$\frac{5}{6}( \frac{1}{2}x+ 6)-3x$

We plug in x=12

. That means we substitute 12 wherever we see x to obtain,

$\frac{5}{6}( \frac{1}{2}\times 12+ 6)-3\times 12$

We simplify the parenthesis first to obtain,

$=\frac{5}{6}( 6+ 6)-36$

$=\frac{5}{6}( 12)-36$

$=5\times 2-36$

=10-36

Hence the expression evaluates to =-26

-26

Step-by-step explanation:

We are given an expression $\frac{5}{6} (\frac{1}{2} x+6)-3x$ and we are to find its value when x is equal to 12.

So we will substitute 12 in place of x and solve it to get:

$\frac{5}{6} (\frac{1}{2} x+6)-3x$

$=\frac{5}{6} (\frac{1}{2} *12+6)-3(12)$

Solving inside the brackets first:

$=\frac{5}{6} (6+6)-36$

$=\frac{5}{6} (12)-36$

=5*2-36

=-26

Therefore, the value of the given expression when x is equal to 12 is -26.
