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

D is your answer
Step-by-step explanation:
Juan went slower because it took him more minutes to go the same distance at Rita. She went 8 miles in 8 minutes. Juan went 8 miles in like 17 minutes
10 to the -5.....again...numbers follow the decimal so move to the right and therefore always negative.
