Answer:
8
Step-by-step explanation:
The answer would be 8 because the question would be
24 ÷ x + 5 × 3 + 2=20 right?
The first thing you would want to do is multiply the 5 and the 3 because of PEMDAS which should give you 24 ÷ x + 15 + 2 = 20.
15 plus 2 is 17 and then you would subtract 17 from 20 which would give you 3. So you know know that 24÷x has to be 3 and 24÷3 is 8 so x=8.
Hope this helped!

Answer:
I'm so sorry I can't help but you can try and use math-way to answer anyquestions regarding equations and such!
Answer:
R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]
Step-by-step explanation:
Squaring both sides of equation:
I^2 = (ER)^2/(R^2 + (WL)^2)
<=>(ER)^2 = (I^2)*(R^2 + (WL)^2)
<=>(ER)^2 - (IR)^2 = (IWL)^2
<=> R^2(E^2 - I^2) = (IWL)^2
<=> R^2 = (IWL)^2/(E^2 - I^2)
<=> R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]
Hope this helps!
