Answer:

The number of cats an frogs

Step-by-step explanation:

For some reason the equation has (c+f) grouped off from the rest, since in an equation the first step is to take care of things in the parentheses, first you must add the two together, and based on the description, you know that c is the number of cats and f is the number of frogs.  Therefore adding them together would get the total number of cats and frogs.

Two common names for streets are FirstFirst Street and MainMain ​Street, with 14 comma 86614,866 streets bearing one of these
oksian1 [2.3K]

Answer:  There are 7,677 streets named as " First Street" and 7, 189 streets named as  "Main Street" .

Step-by-step explanation:

Let x be the number of streets named as First Street .

y be the number of streets named as Main Street.

AS per the given information, we have the following system of equations :

x+y=14866-------------(1)\\\\x=488+y-------------(2)

Substitute the value of x from (2) in (1) , we get

488+y+y=14866\\\\ 2y =14866- 488\\\\ 2y=14378\\\\ y=7189

Put value of y in (2), we get

x=488+7189=7677

Hence , there are 7,677 streets named as " First Street" and 7, 189 streets named as  "Main Street" .

According to the table, Tasha initially had blank dollars before purchasing songs, and the cost of each song was blank dollars
melomori [17]

Total money before purchasing = $30

Cost of each song = $1.20

Solution:

According to the table,

No. of songs    Amount

        2                 27.60

        3                 26.40

        4                 25.20

Difference between amount she have after bought 3 songs to 2 songs:

27.60 – 26.40 = 1.20

Difference between amount she have after bought 4 songs to 3 songs:

26.40 – 25.20 = 1.20

So, the cost of each song = $1.20

Amount of money she had after purchasing one song = $27.60 + $1.20

                                                                                          = $28.80

Tasha initially had before purchasing songs = $28.80 + $1.20

                                                                         = $30

Hence Tasha initially had $30 before purchasing songs and the cost of each song was $1.20.
