Question

Evaluate the expression 3b-ac when a= -2,b=3,and c=0.5

Answer 1

Answer: 10

If there is no sign between numbers, it means there is multiplication.

3b-ac = 3 * b - a * c

1. Replace values:
3 * 3 - (-2) * 0.5 =
9 + 2 * 0.5 =
9 + 1 = 10

So the answer is 10.

Answer 2

The evaluation of the expression 3b - ac when a=-2, b=3, and c=0.5 is 10.

Step-by-step explanation:

The expression 3b - ac can be evaluated by substituting the given variables a, b, and c with the respective values of -2, 3, and 0.5 provided in the question. First, we calculate 3b which gives us 3*3 = 9. Next, we compute ac, which is -2 * 0.5 = -1. Then, we perform the subtraction 3b - ac = 9 - (-1) = 9 + 1 = 10. So, the answer to the expression 3b - ac using the given variable values is 10.
