Answer:
421 3/50 - 212 9/10 = 208.16 or 5204/25
Step-by-step explanation:
To solve the expressions you could change the values into an improper fraction to solve easily
421 3/50 - 212 9/10 =
421 3/50 = 421 × 50 + 3 / 50 = 21053/50
212 9/10 = 212 × 10 + 9 / 10 = 2129/10
subtract the fractions as follows
21053/50 - 2129/10 =
common factor of the denominator is 50
21053 - 10645 / 50 =
subtract 10645 from 21053
10408/50 = 5204/25 in fraction or 208.16 in decimal
3/50 = 0.6
9/10 = 0.9
Then you would just subtract the values.
421.6 - 212.9 = 208.7

From a list of ten books, 210 ways to select a group of 4 books.
What is a combination?
A combination is a selection of all or a portion of a group of items, regardless of the sequence in which the items are chosen.
The number of ways to select a group of 4 books from a list of 10 books can be calculated using the combination formula:
nCr = n! / (r! x (n-r)!)
Where n is the total number of items (in this case, 10 books) and r is the number of items to be selected (in this case, 4 books).
Plugging in the values, we get:
10C4 = 10! / (4! x (10-4)!)
= 10! / (4! x 6!)
= (10 x 9 x 8 x 7) / (4 x 3 x 2 x 1)
= 210
Therefore, there are 210 ways to select a group of 4 books from a list of 10 books.

First you have all ten books, but then every time after, you loose one because you can't put the same book in the group twice.
10 * 9 * 8 * 7 = 5040 groups

So m=3 where m is the slope. As you go across by 1 you go up by 3
I think you would use y-y1=m(x-x1)
Using (4,2) =y-2=3(x-4)
y-2=3x-12
y=3x-10
