I am stuck at the last line of this problem. The original formula is
R=Rf+B(Rm-Rf)
I have moved it and placed the known information in
14=Rf+1.45(11.5-Rf)
Then moved it further
14=Rf+16.68-1.45Rf
I need to solve for Rf, but I am having a hard time remembering where to start at!! Thanks for your help!
14-16.68=-.45Rf
Rf=2.68/.45
To solve for Rf in the equation 14=Rf+16.68-1.45Rf, you can follow these steps:
1. Start by collecting similar terms. Combine the terms that have Rf:
-14 + 16.68 = Rf - 1.45Rf
2. Simplify the equation further:
2.68 = 0.55Rf
3. Divide both sides of the equation by 0.55 to isolate Rf:
2.68 / 0.55 = Rf
4. Calculate the value of Rf:
Rf ≈ 4.873
So, the value of Rf is approximately 4.873.
