Evaluate 8p +3q-18, when p=1/2 and q=7.

Substitute Values: Substitute the given values of p and q into the expression. We have p = 1/2 and q = 7. The expression is 8p + 3q - 18. Let's substitute the values: 8 * (1/2) + 3 * 7 - 18Perform Multiplication: Perform the multiplication for each term. Now we calculate each term separately: 8 * (1/2) = 4 3 * 7 = 21 So the expression becomes: 4 + 21 - 18Add and Subtract: Add and subtract the numbers to find the value of the expression. Now we add and subtract the numbers: 4 + 21 = 25 25 - 18 = 7 So the value of the expression is 7.

Q. Evaluate

8p +3q-18

, when

p=\frac{1}{2}

and

q=7

Substitute Values: Substitute the given values of $p$ and $q$ into the expression. $\newline$ We have $p = \frac{1}{2}$ and $q = 7$ . The expression is $8p + 3q - 18$ . Let's substitute the values: $\newline$ $8 \times \left(\frac{1}{2}\right) + 3 \times 7 - 18$
Perform Multiplication: Perform the multiplication for each term. $\newline$ Now we calculate each term separately: $\newline$ $8 \times \left(\frac{1}{2}\right) = 4$ $\newline$ $3 \times 7 = 21$ $\newline$ So the expression becomes: $\newline$ $4 + 21 - 18$
Add and Subtract: Add and subtract the numbers to find the value of the expression. $\newline$ Now we add and subtract the numbers: $\newline$ $4 + 21 = 25$ $\newline$ $25 - 18 = 7$ $\newline$ So the value of the expression is $7$ .
