Polly and her friends want to make matching outfits for twin day at school. they have 51 yards of cloth. if each outfit requires 2 2/5 yards of material, how many outfits can they make?

21

Step-by-step explanation:

Total cloth length = 51 yards

Cloth requirement for each outfit = 2 2/5 = 12/5 yards

Total possible number of outfits can be calculated by dividing to total cloth length by the length of each outfit.

Total outfits = 51/ (12*5)

=>  (51*5)/12

=> 21.25

As the number of suits is always an interger, so the total number of outfits made by 51 yards of clocth are 21

22, 28, 34, 40, 46

b)   f(n) = 6n + 16

n = what is the number of the row ( 22 would be row 1) so if we replaced n with 1, we would get 22

c)   the 14th row will have 100 seats

(1)   (2)   (3)   (4)   (5)   (6)   (7)   (8)   (9)   (10) (11) (12) (13) (14)

22 | 28 | 34 | 40 | 46 | 52 | 58 | 64 | 70 | 76 | 82 | 88 | 94 | 100
