Question

evaluating expressions with multiple variables: fractions & decimals
evaluate (\frac{1}{4}c + 3d) when (c = 6) and (d = 7).

Explanation:

Step1: Substitute c and d values

Substitute \( c = 6 \) and \( d = 7 \) into the expression \( \frac{1}{4}c + 3d \).
\( \frac{1}{4} \times 6 + 3 \times 7 \)

Step2: Calculate each term

First, calculate \( \frac{1}{4} \times 6 \): \( \frac{6}{4} = 1.5 \)
Then, calculate \( 3 \times 7 = 21 \)

Step3: Add the results

Add the two results together: \( 1.5 + 21 = 22.5 \)

Answer:

\( 22.5 \)
