Answer:
1423/33
Step-by-step explanation:
Let x = 43.121212.........
Two digits are repeating after decimal point. So multiply both sides by 100
100x = 4312.1212 --------------(I)
<u> x = 43.1212 </u> -----------(II) { subtract equation (II) form (I)}
99x = 4269
x= 4269/99 {reduce to simplest form by giving by 3rd table}
x = 1423/33

Answer:
16 = 2x
Step-by-step explanation:
The pattern for a direct variation equation is y = kx
y is the "output" or result
k is the "constant" a number that doesn't change in the equation.
x is the "unknown" variable that makes the output of the equation true when found.
Here x=8
16 = 2(8)
The answer would be D.
