Evaluate $2c-3b$ when $c=8$ and $b=3.5$ . Then, find the values of $10.5$ , $2$ , $13$ , and $-5.5$ .

STEP 1

Assumptions
1. The expression to evaluate is $2c - 3b$ .
2. The value of $c$ is given as 8.
3. The value of $b$ is given as 3.5.

STEP 2

Substitute the given values of $c$ and $b$ into the expression.
$2c - 3b = 2(8) - 3(3.5)$

STEP 3

Perform the multiplication for each term.
$2(8) = 16$ $3(3.5) = 10.5$

STEP 4

Substitute the results of the multiplication back into the expression.
$2c - 3b = 16 - 10.5$

STEP 5

Subtract the second term from the first term.
$16 - 10.5 = 5.5$
The value of the expression $2c - 3b$ when $c=8$ and $b=3.5$ is 5.5.
