Answer:
1 1/4
Step-by-step explanation:
You are multiplying a fraction by a mixed number so you have to turn the mixed number into an improper fraction.
2 1/2 -- to do this you have to multiply the denominator by the whole number, then add the numerator.
2*2= 4 4+1=5
2 1/2 = 5/2
Then, you multiply normally
1/2 x 5/2 = 5/4
5/4= 1 1/4
So, you answer would be 1 1/4
Hope this helps!!

Answer:
Adam is 9 years old.
Step-by-step explanation:
Let d and c represent Adam's and Alicia's ages.
d = c - 15, and
c + 6 = 2(d + 6)
Rearrange d = c - 15 as c = d + 15, and then substitute d + 15 for c in the second equation. We obtain:
d + 15 + 6 = 2(d + 6), or
d + 21 = 2d + 12
Combining like terms, we get 21 = d + 12, or 9 = d.
If d = 9 then c = d + 15, or c = 9 + 15, or c = 24.
Adam is 9 years old.

Answer: 9/38</h3>
Reason:
There are 10 red cards out of 10+10 = 20 total.
10/20 = 1/2 is the probability of selecting a red card.
If the red card is not put back (i.e. "no replacement"), then the chances of getting another red card is (10-1)/(20-1) = 9/19
Multiply the two fractions mentioned to get the final answer.
(1/2)*(9/19) = (1*9)/(2*19) = 9/38
