Question

evaluate the expression when c = -1 and d = 15

c - d/-2

Answer 1

To evaluate the expression \( \frac{c - d}{-2} \) when \( c = -1 \) and \( d = 15 \), we can follow these steps:

1. Substitute the values of \( c \) and \( d \) into the expression:

\[
\frac{-1 - 15}{-2}
\]

2. Simplify the expression in the numerator:

\[
-1 - 15 = -16
\]

So the expression now looks like this:

\[
\frac{-16}{-2}
\]

3. Now, perform the division:

\[
\frac{-16}{-2} = 8
\]

Thus, the evaluated expression is \( 8 \).
