First, let's reduce our fractions to their simplest forms.
4/5 is already in its simplest form
16/20 = 4/5.
Now that both of por fractions are in their simplest forms, let's compare them.
4/5 is equal to 4/5
D is the correct answer.
The best first step
for the elimination method would be: <span>1. multiply the first equation by 2 and the second equation by 3.
</span><span>
2x - 6y = 2 /*2
5x + 4y = 28 /*3
____________
4x - 12y = 4
15x + 12y = 84
____________
4x - 12y + 15x + 12y = 4 + 84
19x = 88
x = 88/19

Answer:
x = 16.2
Step-by-step explanation:
5/9 = 9/x
5x = 81
x = 16.2
Answer:
5/11 amperes ≈ 0.455 amperes
Step-by-step explanation:
The applicable formula for the current (I) is ...
I = P/V . . . . where P is power in watts, and V is voltage in volts
I = (50 watts)/(110 volts) = 5/11 amperes
