Answer:
x = 200/3
Step-by-step explanation:
x/10 = 200/30
x × 30 = 200 × 10
30x = 2000
x = 2000 ÷ 30
x = 200/3
Thus, The value of x is 200/3

Answer:
The correct answer is: Option D: 8
Step-by-step explanation:
Given that she spent $208 on the sewing machines
And
the equation for profits to break even is:
208 + 10x = 36x
In order to find the number of purses to break even, we have to find the value of x
So,

Subtracting 10x from both sides

Dividing both sides by 26

The number of purses is 8
Hence,
The correct answer is: Option D: 8
They are not
It goes from
0/0 1/3 2/5 3/6(or 1/2) which are not the same. This makes them not proportional to one another. (I think)
