Answer 1

           $\rule{50}{1}\large\blue\textsf{\textbf{\underline{Question:-}}}\rule{50}{1}$

       Evaluate 1/4c+3d when c=6, and d=7.

        $\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

       Replace c with 6, and d with 7:-

     $\Large\displaystyle\frac{1}{4} (6)+3(7)$

$\bigstar$ On simplification,

   $\Large\displaystyle\frac{1}{4} \times\frac{6}{1}+21$

$\bigstar$ On further simplification,

    $\Large\displaystyle\frac{6}{4} +21$

$\bigstar$ On further simplification,

     $\Large\displaystyle\frac{6}{4}+\frac{84}{4}$

$\bigstar$ Adding the numerators,

$\Large\displaystyle\frac{90}{4}$

$\bigstar$ Finally, Reducing the fraction:-

$\Large\displaystyle\frac{45}{2}$

Answer 2

Answer:

SolutioN :

• Just plug in the values of c & d in the given expression and calculate :

$\longrightarrow \bf \: \frac{1}{4} \times 6 + 3 \times 7$

$\longrightarrow \boxed{\bf{ \frac{45}{2} }}$

• Our final answer is 45/2 .
