Ok I can help just tell me the problem
<span>f(x) = 5(1/5)-x
f(x) = 5(5)x</span>
The answer for your question is 686
The answer is B) 4:5
First write the ratio out. To find the simplified expression, divide by the greatest common factor (GCF). In this case, the GCF of 28 and 35 is 7.
28:35
--- ----
7 7
=4:5
4:5 is the simplest form because you cannot simplify it further.
1^81, 9^2, 3^4. the others are rather to high or to low
