Answer:
a = 1
Step-by-step explanation:
First, you subtract 6 from both sides and you end up with a² = 1. Since one cannot be squared or square rooted, a = 1. I hope this helps!
its B Step-by-step explanation:
3 x 4 = 12
12/12 - 1/3 ( so 4/12) = 8/12
8/12 - 1/4 ( so 2/12 as you only have 8/12 left) = 6/12
Answer = 6/12 = 1/2 or 50%
There are 5 cards less than nine that are prime, so there is a 5/9 chance of picking the first one prime. The second one would be 4/8 or 1/2, because you have removed a card from the deck. You multiply them together to get: 5/18.
Hope this helps!
