Eva and Dulcina have 82 pins together. Dulcina has 34 more pins than Eva. How many pins are in Dulcina’s collection? How many pins are in Eva’s collection?

Eva has 24 pins in her collection. Dulcina has 58 pins in her collection.

Step-by-step explanation:

x= number of pins Eva has in her collection

x + (x+34)=82 pins total

2x+34=82

x=24

24+34=58

dulcian has 27.88 pins and eva has 54.12 pins

Step-by-step explanation:Get 82-34% then get the answer from that then you get 82 minus that answer you got from 82-34 then you get the answer from that which would be 27.88 and then subtract that from 82 and you get 54.12 So then dulcina gets27.88 and eva has54.12 pins.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
