If you are solving for c you need to divide both sides of the inequality by -5 so c< (or equal to) -30/-5 or c<(or equal to)7
B- use Desmos it helps a lot!
So 12/15 simplifies to 4/5, and if you multiply both sides by two you have 8/10 so i guess 2 ( and some extra )
There are 52 cards in the deck.
Picking a spade would be 13/52 which reduces to 1/4
After the first card is picked there are 51 cards left, picking a club would be 13/51
Picking both would be 1/4 x 13/51 = 13/204
The answer is C.
