Answer:
rock: not rock
7:13
Step-by-step explanation:
First determine how many songs are not rock
60-21 = 39
There are 39 songs that are not rock
ratio of rock to not rock
rock: not rock
21:39
We can divide by 3
21/3:39/3
7 : 13
the length of each equal side is 10 ft
the length of the third side is 2 ft
let x be the length of the third side the equal sides are 4x + 2
given perimeter == 22, then
x + 4x + 2 + 4x + 2 = 22
9x + 4 = 22 ( subtract 4 from both sides )
9x = 18 ( divide both sides by 9 )
x = 2 and 4x + 2= 10
