Let the number be xy ,
xy = 10x + y. when reversed = yx = 10y + x
x = 2y ........(a)
10x + y + 10y + x = 66.........(b)
10(2y) + y + 10y + 2y = 66
20y + y + 10y + 2y = 66
33y = 66
y = 66/33
y = 2
x = 2y = 2*2 = 4
Recall the original number is xy = 42.
Answer:
1. (3) 2. (4) 3. (-1)
Step-by-step explanation:
if you graph them then you get the answer.
The current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A
<h3>Ohms law</h3>
The current passing through a conductor is proportional to the potential difference. Mathematically;
V = IR
where
V is the voltage = 120V
R is the resistance = 11.5 ohms
Required
Current I
Substitute
I = V/R
I = 120/11.5
I = 10.4A
Hence the current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A
