Jeanette has 3 quarters and 6 dimes in her hand. she accidentally drops one of the coins. what is the probability that the coin she drops if a dime? A. 1/2
B. 2/3
C. 2/1
D. 1/9

2/3

Step-by-step explanation:

There are a total of (3+6) = 9 coins

P( dime) = dimes / total

              = 6/9

              = 2/3

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

i think asking google will you get the answer to that question
