Question

Evaluate the expression 10 + 2p - 3r, when p=3 and r=-2

Answer 1

The expression 10 + 2p - 3r, with p=3 and r=-2, is evaluated by substituting the given values which results in an answer of 22.

Step-by-step explanation:

The student has been asked to evaluate the expression 10 + 2p - 3r, given the values of p = 3 and r = -2. We will substitute these values into the expression as follows:

10 + 2(3) - 3(-2)

First, multiply 2 by 3 (for 2p) and -3 by -2 (for -3r):

10 + 6 + 6

Now, we add all terms together:

10 + 6 + 6 = 22

The evaluated expression equals 22.
