12
-5
-15.5
24

Answer 1

The evaluation of the expression is 12.

Evaluation of expression.

Evaluation of expression simply means substitution of values into the variables in the expression.

Here, we are given an expression 3b - ac. It was stated that the value of a = 2, b = 3, and c = -1.5.

Replacing these values into the equation, we have:

= 3(3) - 2(-1.5)

= 9 + 3

= 12

Therefore, we can conclude that the evaluation of the expression is 12.
