Answer:
C=22X+5Y
Step-by-step explanation:
Probability(both marbles are red) = 5/12 * 4/11 = 20/132
= 5/33 Answer
1st add 7 to both sides : 3z = 21, 2nd divide both sides with 3: z = 7
Answer:
18 nickels, 9 dimes, 6 quarters.
Step-by-step explanation:
Basically, I just made a money table and used it to get my equation, which is: 60x-30=330, to get how many quarters there are. Then, plug that in to the problem and you have your answer.
20x+3
This shouldddd be the answer sorry if I’m wrong, but if you group all the x variables together they add up to twenty, then you just add “+3” being that it has no x and therefore must be put in some form of separate group!
