HELP PLEAS it’d be rlly appreciated Maeve has 45 coins, all nickels and dimes. The total value of her coins is $3,60. How many nickels and
dimes does she have?

they have

et n = number of nickels

Let d = number of dimes

given:

(1) +n+%2B+d+=+45+

(2) +5n+%2B+10d+=+360+

Multiply both sides of (1) by 5

and subtract (1) from (2)

(2) +5n+%2B+10d+=+360+

(1) +-5n+-+5d+=+-225+

+5d+=+135+

+d+=+27+

and, since

(1) +n+%2B+d+=+45+

(1) +n+%2B+27+=+45+

(1) +n+=+45+-+27+

(1) +n+=+18+

She had 18 nickels and 27 dimes

check:

(2) +5%2A18+%2B+10%2A27+=+360+

(2) +90+%2B+270+=+360+

(2) +360+=+360+
