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

c - d/-2

1 answer

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:

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

  1. Simplify the expression in the numerator:

\[ -1 - 15 = -16 \]

So the expression now looks like this:

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

  1. Now, perform the division:

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

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