Will there be any leftover pencils? If so, then how many pencils will be leftover? Please explain how you found your answer mathematically.
please I need help I will mark you brainlist

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257

How do i do this? i don’t understand

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.
