I think it would be y plus 3 times 2 equals 5x. I'm not sure if that is what they are asking for.
She forgot the 0 in the middle, which is why she got 192. The correct answer is 1812
Im not sure but I would think you would divide 75 by .15. That would get you 500. So 500 minutes would be your answer.
For this case we have the following equation:
V = I * R
Where,
V: voltage
I: current
R: resistance
By clearing R we have:
R = V / I
Substituting the values:
R = (20) / (0.57)
R = 35.09 Ohms
Answer:
The resistance of the light bulb is:
R = 35.09 Ohms
