Answer:
She has 9 5 cent stamps and 6 7 cent stamps.
Step-by-step explanation:
Let the number of five cent stamps be represented by F and the number of seven cent stamps be represented by S.
The difference between the number of five cent and seven cent stamps is 3
F-S=3
The sum of the collection from each type of stamp is 87 cents
5F+7S=87
Let us solve the equations simultaneously.
F-S=3
5F+7S=87
Using substitution method,
F= 3+S
5(3+S)+7S=87
15+5S+7S=87
12S=87-15
12S=72
S=6
F=3+S
=3+6=9
Therefore the number of five cent stamps is 9 and seven cent stamps is 6.
You can tell if 2 fractions are equivalent if they are on the same place on this number line. Because 3/8 and 1/2 aren't on the same line, they aren't equal. Contrastingly, because 4/8 and 1/2 ARE on the same line, they are equivalent fractions.
Hope this helps :)
