Answer :

Sure, let's evaluate the expression [tex]\( 3w + (8 - v)t \)[/tex] step by step given the values [tex]\( w = 4 \)[/tex], [tex]\( v = 5 \)[/tex], and [tex]\( t = 2 \)[/tex].

1. Substitute the given values into the expression:
[tex]\[ 3 \cdot 4 + (8 - 5) \cdot 2 \][/tex]

2. Perform the multiplication inside the first term:
[tex]\[ 12 + (8 - 5) \cdot 2 \][/tex]

3. Simplify the expression inside the parentheses:
[tex]\[ 12 + 3 \cdot 2 \][/tex]

4. Perform the multiplication inside the second term:
[tex]\[ 12 + 6 \][/tex]

5. Add the results:
[tex]\[ 18 \][/tex]

So, the value of the expression [tex]\( 3w + (8 - v)t \)[/tex] when [tex]\( w = 4 \)[/tex], [tex]\( v = 5 \)[/tex], and [tex]\( t = 2 \)[/tex] is [tex]\( 18 \)[/tex].
