you would do 7/12 which is 0.5833333333

Answer:
Dulcina's collection has 57 pins
Eva's collection has 25 pins
Step-by-step explanation:
first we are going to represent the relation of pins by means of an equation
d = Dulcina
e = Eva
e + d = 82
and now we represent the relation of the collections of each one
d = e + 32
having the 2 equations we can replace the d by (e + 32) and place it in the other equation
e + d = 82
e + (e + 32) = 82
2e + 32 = 82
2e = 82 - 32
2e = 50
e = 25
Now we replace e with 25 in the second equation and get the value of d
d = e + 32
d = 25 + 32
d = 57
Answer:
ok we know the box means 90 degrees and one corner is 63 degrees so in order to get 180 degrees we add 90+63 which is 153 then we take that away from 180 so the answer is <u>17</u>
