SAT Math Multiple Choice Practice Question 569: Answer and Explanation
5. If , and , what is the value of p ?
Correct Answer: E
E Only s is equal to a number without a variable, so plug that into the equations in the question. The value of s is negative. The variable r is positive, because r = ?, and when ? takes the place of s, the negative signs cancel out: and r = 4. Because r is positive, q is negative: q = ? becomes q = ?. Finally, because q is negative, p is positive: p = ?, then and p = 4.
