The boiling point of benzene is 176° F, and the freezing point is 42° F. Write an inequality to represent the temperatures the benzene must stay between to ensure it remains liquid.

Hey there,

In order for it to stay a liquid, the substance has to be above 42 degrees and below 176 degrees. Therefore,

the inequality would be 42<x<176 degrees. You can't use a less than or equal to sign for these since they can't be equal to those values.

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
