Answer:
45 different sets
Step-by-step explanation:
There are 10 numbers in {0,1,2,3,4,5,6,7,8,9}.
We are looking for a combination since order doesn't mater
There are 10 options for the first number
We have chosen 1
Now there are 9 numbers
10*9
But since order doesn't matter, we divide by 2
The set {1,2} is the same as the set {2,1}
90/2 = 45
90
it is 90 because in the first slot there can be any 10 numbers and in the second slot the set can contain any of the remaining 9 numbers and then we can multiply these two numbers together to find the total amount of sets.
hope this helps :)
Hello there! In normal form it would be 213/412 but in simplest form there is no fraction.
There is no simplest form for this fraction

3 necklaces and 12 bracelets
Bracelets = x +4
amount of necklace gold = 20*x
amount of gold in bracelet = 7*(x+4)
added together = 109 gm
20x + 7(x+4) = 109
20x + 7x+28 = 109
27x+28=109
-28 -28
27x= 81
/27 /27
x=3 necklaces
then bracelets = 3+4=12
this is 52 degrees
I think that would be 1
Do everything in the lines before anything else. -2 becomes a 2 and then you add that with the 12 and divide 12 on both sides to get one.
its 11
