Consider this expression 5/6(1/2x+6)-3x<br> What is the value of the expression evaluated for x=12
just olya [345]
ANSWER

The correct answer is -26

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

=-26

Hence the expression evaluates to =-26
