The correct answer is 15
<span>4 + (x/3) = 9 </span>
<span>(x/3) = 9 - 4 </span>
<span>(x/3) = 5 </span>
<span>x = 15 </span>
a) if the two gloves someone receives might both be for the left hand or right hand.
b) if each sister gets one left and one right.
Soln:
a) So i thought about dissectng the problem first into finding the number of ways in which I could make pairs of gloves:
C(12, 2)
then I asked how many ways could the sets of gloves be assigned amongst the 6 sisters:
<span><span>6!</span><span>6!</span></span>
and taking the product of this would give me the amount of ways this could occur:
= C(12,2) * 6!
then for part b)
using this same idea except:
C(6,1) C(6,1) for the left and right glove each .
the C(6,1)*C(6,1)*6!
Right way to think them through?
X, y - the numbers
The numbers multiply to 100.
The numbers add up to -29.
Substitute -x-29 for y in the first equation:
The numbers are
-4 and
-25.
I believe the answer is x=14
Just put the T's by adding and subtracting on one side and the numbers on the other side then divide the number with the magnitude of the final T you got
