<span>Answer: 4
Explanation:
Translate the english language to mathematical (algebraic) language.
This implies to define the variables and translates the statements into equations.
1) Adventure
Play sells an mp3 player for $18.00 and charges $3.25 per song.
Cost = price of the mp3 player + price each song * number of songs
Variables:
number of songs: n
price each son: $3.25
price of the mp3 player: $ 18.00
Cost: c(n), this means that the cost is a function of n.
c(n) = 18 + 3.25n
2) King
Music sells a player for $23.00 and charges $2.00 per song. For how many
songs will the cost be the same?
Using the same procedure used for Adventure Play case:
c(n) = 23 + 2n
3) Equal cost =>
18 + 3.25n = 23 + 2n
=> 3.25n - 2n = 23 - 18
=> 1.25n = 5
=> n = 5 / 1.25
=> n = 4
Answer: the cost will be the same for 4 songs.

List factors of each:
60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
45: 1, 3, 5, 9, 15, 45
The largest common value is 15
The greatest possible length of each is 15 cm
Answer: 15 cm.
Slope = 75
Y-intercept = 150
27⅛ ÷ 3½
in my opinion, turning it into a decimal is easier
27 ⅛ = 27.125
3 ½ = 3.5
so.....
27.125 ÷ 3.5 = 7.75 which is also 7 ¾
I think the last one is right hope this helps
