Answer:
Step-by-step explanation:
No. Of quarters n(Q)= 3
No. Of dimes n(D) = 5
No. Of nickels n(N) = 2 
Total T = 3+5+2 = 10
Prob(D) = n(D)/T = 5/10 = 1/2
Now there are 9 left since it is not replaced back
Prob(Q) = 3/9 = 1/3
Prob(D and Q) = 1/2 × 1/3 = 1/6

(7x-10) - (-6x-8)
distribute the negative to the (-6x-8)
(7x-10) + 6x+8
disregard the parenthesis because addition is associative 
7x-10 + 6x+8
combine like terms
13x-2
13x-2 is the answer
