Answer: D
Step-by-step explanation:
Paul's Current score is 42, x = paul's awaiting score
Paul's score has to be greater than 174
Current score plus awaiting score must be greater than 174
Answer:
d. 42 + p > 174
Step-by-step explanation:
Since Paul needs to score more than 174, the sign needs to be > and not ≥ because he does not want to equalize the score of 174.
Since he currently has a score of 42, he needs to add another score. Assuming the next score he needs is p,
42 + p is the equation.
