Evaluate the expression for p = 7, q = –5, and r = –5. Simplify your answer.

Question

qr + p
4
=

Answer 1

To evaluate the expression \( \frac{qr + p}{4} \) for the values \( p = 7 \), \( q = -5 \), and \( r = -5 \), we first need to compute \( qr \) and then add \( p \).

1. Calculate \( qr \): \[ qr = (-5)(-5) = 25 \]

2. Next, add \( p \): \[ qr + p = 25 + 7 = 32 \]

3. Now, divide by 4: \[ \frac{qr + p}{4} = \frac{32}{4} = 8 \]

So, the simplified answer is \( 8 \).
