Since these events are independent, you add the possibilities
the number of cards less than 9 is 32
the number of spades is 13
there are 52 cards in a deck, so you put those numbers over 52
32/52 + 13/52 = 45/52
the answer is 45/52

This question implies the constant rate or proportion of water to mass. Therefore, we can set up the following equation:

Answer:
10 and 13
Step-by-step explanation:
Let the two numbers be p and q. p = (1/2)q + 8. p + q = 23. Substituting (1/2)q + 8 for p, we get (1/2)q + 8 + q = 23.
First, subtract 8 from both sides, obtaining (1/2)q + q = 15.
Next, mult. all terms by 2 to eliminate the fraction (1/2): q + 2q = 30.
Then 3q = 30, and q = 10. Then p = (1/2)(10) + 8 = 5 + 8 = 13.
The numbers are 10 and 13.
So Abby hasn't received 60% of her order, BUT she already got 80 lobsters, hmmmmm well, 100% - 60% is just 40%, so she already got the 40%, which incidentally is 80 lobsters. Let's say the whole order, or 100% of it is "x" lobsters.
if 80 lobsters are 40%, what is "x"?
