After 5s, the pressure on a valve is less than 60lb/in.2 (pounds per square inch). Using t to represent time and p to represent pressure, this statement can be written “for t > 5 s, p < 60lb/in.² .” In this way, write the statement “when the current I in a circuit is less than 4A, the resistance R is greater than 12 Ω (ohms).”
