To create the new expression based on the teacher's instructions, let's break down the statement:
- "3 times this value": This refers to multiplying a variable (let's call it \( x \)) by 3, resulting in \( 3x \).
- "Take away 5": This indicates subtraction, so you have to subtract 5 from the result of the previous step.
Putting it all together, the new expression can be written as:
\[ 3x - 5 \]
If \( x \) represents the value used in the expression, this represents three times that value minus 5. You can replace \( x \) with any specific number if you have it. If not specified, \( 3x - 5 \) is the completed expression based on the given instructions.
