Bianca has a stamp collection of 5 cent stamps and 7 cent stamps. she has 3 less 7 cent stamps as 5 cent stamps. if the collection has a face value of 87 cents, how many of each does she have?
she has 5 cent stamps and 7 cent stamps.

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.

Number of 5 cent stamps = 9

Number of 7 cent stamps = 6

Step-by-step explanation:

We are given that Bianca has a stamp collection of 5 cent stamps and 7 cent stamps in which there are 3 less 7 cent stamps as 5 cent stamps.

If the total face value of stamps is 87 cents, we are to find the number of stamps of each value.

Assuming to be the number of 5 cent stamps and to be the 7 cent stamps so we can write it as:

--- (1)

--- (2)

Substituting this value of from (2) in (1):

Number of 5 cent stamps = 9

Number of 7 cent stamps = 9 - 3 = 6

from the sentence, "tomorrow morning, akiko will arrive an hour late" depicts a third person perspective because it doesn't use any pronoun to replace akiko, the subject of the sentence, and it is in singular form since akiko is only one person.

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
