Answer: x is 20
Step-by-step explanation:
This is ratio
a : c = b : x and d : unknown
a : c = 9 : 12 = 3 : 4 which is 9/12
b : x = 15 : x which is 15 / x
So the proportion will be :
3/4 = 15/x
So Cross multiplying
3x = 90
Divide both side by 3
x = 90/3
x = 20
For this case we must find
By definition we have to:
We have the following functions:
Now, applying the given definition, we have:
Answer:
I believe x=2 because 6x=2x+8
