<span>hi, </span>
<span>you can determine it by seeing if y/x = a constant value, in other words if y = (a constant value) x </span>
<span>then you say that y varies directly with x, and you can see that : call the constant k </span>
<span>then y/x is supposed to be k in all values </span>
<span>6/3 = 2 </span>
<span>24/12 =2 </span>
<span>96/48 = 2 </span>
<span>384/192 = 2 </span>
<span>it worked the ratio between x and y is constant so y varies directly with x ( y = 2x) and that constant k =2 </span>
<span>p.s. you can also say that x varies directly with y but in that case it becomes x/y =constant and that constant say c is 1/2 (x = (1/2)y)) </span>
<span>hope u understand.

There's a simple formula for finding the arc length.
In radians:<span>
A = θ*r = (2pi/3) x 4 cm = 8*pi/3 cm
Therefore, the answer is letter A </span> <span>8*pi/3 cm.
I hope my answer has come to your help. God bless and have a nice day ahead!

12, 21, 39 is the sequence given the given rule. Just plug in n=1, 4, 10 to evaluate each term.
Let x be the price of each large drink. The equation would be:
$12(1) + 3x = $16.95
3x = $16.95 - $12
3x = 4.95
x = 4.95/3
x = $1.65
The answer is B.
<span>I hope I was able to explain it clearly :)</span>
2x-3=-1x+18
+1x +1x
3x-3=18
+3 +3
3x=21
divide both sides by 3
x=7
