3. Matthew has a jar of 368 nickels and dimes he has been collecting. The total value of the coins is $28.40.

Which system of linear equations and solution can be used to represent the number
of nickels and dimes Matthew has in his collection?

x = 12

y = 15

step-by-step explanation:

not me

step-by-step explanation:

i wish i did i would like to get a desert ghost ball python

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
