Variables & expressions: Unit test Evaluate 8j-k+14 when j=0.25 and k=1. ◻

Substitute Values: Substitute the given values for j and k into the expression. We have: j = 0.25 k = 1 The expression is 8j - k + 14. Substitute 0.25 for j and 1 for k in 8j - k + 14. 8j - k + 14 = 8 * 0.25 - 1 + 14Multiply 8 by 0.25: Multiply 8 by 0.25. 8 * 0.25 = 2 Now the expression is 2 - 1 + 14.Subtract 1 from 2: Subtract 1 from 2. 2 - 1 = 1 Now the expression is 1 + 14.Add 14 to 1: Add 14 to 1. 1 + 14 = 15 The final value of the expression is 15.

Q. Evaluate

8 j-k+14

when

j=0.25

and

k=1

\newline

_______

Substitute Values: Substitute the given values for $j$ and $k$ into the expression. $\newline$ We have: $\newline$ $j = 0.25$ $\newline$ $k = 1$ $\newline$ The expression is $8j - k + 14$ . $\newline$ Substitute $0.25$ for $j$ and $1$ for $k$ in $8j - k + 14$ . $\newline$ $k$ $0$
Multiply $8$ by $0$ . $25$ : Multiply $8$ by $0.25$ . $\newline$ $8 \times 0.25 = 2$ $\newline$ Now the expression is $2 - 1 + 14$ .
Subtract $1$ from $2$ : Subtract $1$ from $2$ . $\newline$ $2 - 1 = 1$ $\newline$ Now the expression is $1 + 14$ .
Add $14$ to $1$ : Add $14$ to $1$ . $\newline$ $1 + 14 = 15$ $\newline$ The final value of the expression is $15$ .
