Answer:
230
Step-by-step explanation:
Let <em>x</em> = 0.376376376...
Then 1000<em>x</em> = 376.376376376...
So we have
1000<em>x</em> - <em>x</em> = 376.376376376... - 0.376376376...
999<em>x</em> = 376
<em>x</em> = 376/999
This is the answer to the problem. You basically substitute the -6 in for the f(x)
Set it up in a proportion.
8 (oil)/5 (salad dressing) = x/7
cross multiply to get 11.2
