Question

evaluate the expression for the given value of the variables.
0.5a - 2.3b
a = 13, b = 2

0.5a - 2.3b = \boxed{} (type an
integer or a decimal.)

Explanation:

Step1: Substitute a and b values

Substitute \( a = 13 \) and \( b = 2 \) into the expression \( 0.5a - 2.3b \).
\( 0.5\times13 - 2.3\times2 \)

Step2: Calculate each term

First, calculate \( 0.5\times13 = 6.5 \) and \( 2.3\times2 = 4.6 \).
Then, subtract the second result from the first: \( 6.5 - 4.6 \)

Step3: Find the result

\( 6.5 - 4.6 = 1.9 \)

Answer:

1.9
