Answer:
There are 19 big marbles
Step-by-step explanation:
10a + 3b = 209
a = 3b
3b = 3b
10a + a = 209
11a = 209
a = 209/11
a = 19

Answer:

Step-by-step explanation:
From the image, f(x) and x are rlated by

where b is the common ratio
We first find the value for b





so we can say the common ratio, b=5
we put in any value of f(x) and the corresponding value for x to find a value
Let put x=0 and f(x)=5120
This implies that

but 

Hence a=5120
Thus the equation which model the relationship between the weeks and the viewers is
