Evaluate multi-variable expressions

\mathrm{HC9}

\newline

Find the value of the expression

\newline

14+20 \div v \div 2+w

\newline

for

v=5

and

w=4

.

Substitute values into expression: Substitute the given values for $v$ and $w$ into the expression. $\newline$ Expression: $14 + 20 \div v \div 2 + w$ $\newline$ Substitute $v = 5$ and $w = 4$ . $\newline$ Expression becomes: $14 + 20 \div 5 \div 2 + 4$
Perform first division: First, perform the division $20 \div 5$ . $\newline$ Divide $20$ by $5$ . $\newline$ $20 \div 5 = 4$
Divide result by $2$ : Next, divide the result by $2$ . $\newline$ Divide $4$ by $2$ . $\newline$ $4 \div 2 = 2$
Add result to $14$ : Now, add the result to $14$ . Add $2$ to $14$ . $14 + 2 = 16$
Add $w$ to result: Finally, add $w$ , which is $4$ , to the result. $\newline$ Add $4$ to $16$ . $\newline$ $16 + 4 = 20$
