Step-by-step explanation:
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+
Step-by-step explanation:
Answer:
infinite solutions
Step-by-step explanation:
2(4x+1) −5x +2 = 3x+4
Distribute
8x +2 -5x +2 =3x+4
Combine like terms
3x +4 = 3x+4
Subtract 3x from each side
3x-3x+4 = 3x-3x+4
4=4
This is always true, so there are infinite solutions
