(3)



Answer :

Certainly! Let's break down the statement to form a number sentence using the symbol [tex]\( p \)[/tex] to represent the unknown number. Here's the step-by-step solution:

1. Identify the unknown number: We need to represent the unknown number with the symbol [tex]\( p \)[/tex].

2. Express three times the unknown number: Three times the unknown number can be written as [tex]\( 3p \)[/tex].

3. Subtract 5 from three times the unknown number: If we subtract 5 from [tex]\( 3p \)[/tex], we write it as [tex]\( 3p - 5 \)[/tex].

4. Set up the equation based on the condition given: The problem states that subtracting 5 from three times the number results in 80. So, we set [tex]\( 3p - 5 \)[/tex] equal to 80.

Putting it all together, the number sentence is:
[tex]\[ 3p - 5 = 80 \][/tex]

This is the number sentence derived from the given statement.
