If a >b, then ac> bc true or false?

False

Step-by-step explanation:

a>b

Let c> 0 then ac>bc because we are multiplying by a positive number

if c<0  then ac < bc because we are multiplying by a negative number we have to flip the inequality symbol

Since we do not know the value of c, we have to go with false

the difference between a number and 5 is -2.
