13/18 used common denominator of 90 so 2/9 x 10 and 1/6 x 15 gave me 20/90 and 15/90. Added those and cane up with 35/90. Difference was 65/90 so but could be divided by 5 so my answer came out to 13/18.

marishachu [46]

6x+5y=-15

5y/5= -15/5 - 6x/5

y= -3 -6x/5

Megan picks a card from a deck of cards numbered 1-10 and rolls a number cube. What is the probability she chooses a card with a
ehidna [41]

Answer:

1/20 if there is only those 10 cards in a deck and 1/26 if there is 52 cards in the deck.

Step-by-step explanation:

There is 3/6 chances to roll a die with an even number, aka 1/2. If there are only 10 cards in the deck and only one of them has the number 5, it's 1/10. To find the probability of both these things happening, multiply the probabilities. 1/10 x 1/2 is equal to 1/20. However, since the question doesn't specify if there is 52 cards like a normal deck and 4 5's etc, there can be a different answer because if there's 52 cards in a deck, 4 of them 5's, the chance of getting a 5 is 4/52 or 1/13 and then you multiply that by 1/2 to get 1/26
