Ami and Ria are playing a game where one of them would pick up a card and the other would guess the number. Ami picked up a card
and read the rules to Ria which were: 1. It is an odd number 2. It is a composite number divisible by three different prime numbers. Which of the following would be Ria's correct guess? A: 30 B: 75 C: 189 D: 315
X=-7 divide both side by 3. Any expression divided by itself equals 1. Dividing a positive and a negative equals a negative. Calculate the quotation. Then you get X=-7
