N + 5 > 3n = 37
so you're solving for n?
There are two methods to do this:
1. 2(x + 1) = 38
2*x + 2*1 = 38 (Expand the bracket)
2x + 2 = 38
2x = 36 (Subtract 2 from both sides)
x = 18 (Divide each side by 2)
2. 2(x + 1) = 38
(x + 1) = 19 (Divide each side by 2)
x = 18 (Subtract 1 from each side)
Solution:
Fabric possessed by Da. Shari = 4 Sweaters + 2 Coats + 5 Jackets= 11 in all
Arrangement that Da Shari wants to arrange 4 Sweaters + 2 Coats + 5 Jackets is to put "a sweater first and a jacket last".
After putting a sweater first and jacket last , total fabric which needs to be arranged is (3 Sweaters + 2 Coats + 4 Jackets)=9 in all.
Total number of possible arrangement = (1 sweater) × [9 fabric=(3 Sweaters + 2 Coats + 4 Jackets) arrangement] × (1 Jackets)
= 1! × 9 ! × 1!
= 9 !
= 9 × 8 × 7× 6× 5× 4× 3×2×1
= 362,880 ways
4+6=10 6/10 60% that is the answer
