Question

problem 4
on the math test, rita got 8 more correct answers than sam. sam got 31 questions right. how many answers did rita get right on the math test? which of the equations below represents this situation?
a. r + 8 = 31
b. 8 + 31 = r
c. r - 8 = 31
d. 31 - 8 = r

Explanation:

Step1: Define variables

Let \( r \) be the number of correct answers Rita got. Sam got 31 correct answers, and Rita got 8 more than Sam.

Step2: Form the equation

To find Rita's correct answers, we add 8 to Sam's correct answers (31). So the equation is \( r = 31 + 8 \) or \( 8 + 31 = r \).

Answer:

B. \( 8 + 31 = r \)
