Mark is having a party. he invited 35 people. mark set up 8 tables with 4 chairs at each table. dose mark have enough tablels and chairs for all his guests?

8 * 4 = 32 chairs

No, Mark does not have enough tables and chairs for all of his guests. He only has 32 chairs but there are 35 guests. There are 3 people that will not be seated.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
