Answer:
2.5
Step-by-step explanation:
youll have to multiply 4 times 5/8
18/3.5=5.1 so you do 14/5.1=2.7
so your answer is 2.7 in
17.5x12=210
210 divided by 14=15
15x2.50=37.5
37.5
17.5 is feet so you need to divide by 12 for inches which gets 210 and you need each necklace to be 14 inches so you need to divide 210 by 14 which is 15 each necklace costs 2.50 so you multiply 2.50x15
You get 37.5
The expression should be (2/h)x(k+8).
