Energy = Planck's constant * frequency
= 6.626 * 10^-34 * 5.66 * 10^8
= 3.7503 * 10^-25 Joules
Answer:
The answer is 45
Step-by-step explanation:
The equation is a straightforward one, we have:
2/3x = 30
because we have a fraction on at least one side, we will cross multiply thus:
2x = 30 x 3
2x = 90
Next, we divide both sides by 2 to make x the subject of the formula, we have 2x/2 = 90/2
x = 45
