X = 1st number
x + 1 = 2nd number
x + 2 = 3rd number
x + (x + 1) + (x + 2) = 18...combine like terms
3x + 3 = 18
3x = 18 - 3
3x = 15
x = 5
x + 1 = 5 + 1 = 6
x + 2 = 5 + 2 = 7
7 + 6 + 5 = 18
13 + 5 = 18
18 = 18 (correct)
largest number is 7

3/5 I think is the right number because there’s 60 boys and only 36 of them have a pet.
Answer: 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+
