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?
Step-by-step explanation:
(x, y) is a solution to y = 5/2X
(x, y) is a solution to y=x+3.
The ratio of Y/X is equivalent to 5/2
Point (x, y) is the same point as (5, 2).
A straight line through points (2, 5) and (x, y) will pass through the origin.

Answer:
16 and 4
Step-by-step explanation:
If x is the smaller one, then the larger is 4x. Their sum is ...
x + 4x = 20
x = 20/5 = 4
The two numbers are 16 and 4.
Angle A = angle U since they're both right angles (both 90 degrees). This is what the square marker means.
segment AC = segment UW
Angle C = angle W because they have the same angle marker
---------------------
we have two pairs of congruent angles, with segments between them that are congruent. So we use the ASA property
The final answer is choice E.
Every triangle adds up to 180 degrees
