Evaluate (e)/(4)+2f-3 when e=12 and f=(1)/(2).

Substitute values into expression: Substitute the given values for e and f into the expression. We have e=12 and f=(1)/(2). The expression is (e)/(4)+2f-3. Substitute e=12 into (e)/(4): (12)/(4) = 3. Substitute f=(1)/(2) into 2f: 2*(1)/(2) = 1.Combine results: Combine the results from Step 1 into the expression. The expression now reads 3 + 1 - 3.Perform addition and subtraction: Perform the addition and subtraction in the expression. Calculate 3 + 1 - 3 = 4 - 3 = 1.

Q. Evaluate

\frac{e}{4}+2f-3

when

e=12

and

f=\frac{1}{2}

Substitute values into expression: Substitute the given values for $e$ and $f$ into the expression. $\newline$ We have $e=12$ and $f=\frac{1}{2}$ . The expression is $\frac{e}{4}+2f-3$ . $\newline$ Substitute $e=12$ into $\frac{e}{4}$ : $\frac{12}{4} = 3$ . $\newline$ Substitute $f=\frac{1}{2}$ into $2f$ : $f$ $0$ .
Combine results: Combine the results from Step $1$ into the expression. The expression now reads $3 + 1 - 3$ .
Perform addition and subtraction: Perform the addition and subtraction in the expression. $\newline$ Calculate $3 + 1 - 3 = 4 - 3 = 1$ .
