Answer:
14 blue
Step-by-step explanation:
3/2 = 21/b
3b = 42
b = 42/3
b = 14
100%/x%=27.5/17.16
(100/x)*x=(27.5/17.16)*x
100=1.60256410256*x divide both sides of the equation by (1.60256410256) to get x
100/1.60256410256=x
62.4=x
x=62.4

Step-by-step explanation:
Answer:
(x) = 
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 2x + 1 ( subtract 1 from both sides )
y - 1 = 2x ( divide both sides by 2 )
= x
Change y back into terms of x with x =
(x) , so
(x) =
