The value decimal point is changing going to the right as you divide a number by 10.
For example
=> 2000.3 / 10
notice the decimal point
=> 200.013, the value of decimal numbers increases as the value of whole number decreases.Let’s divide again
=> 200.013 / 10
=> 20.0013 , now we already have 4 digits in our decimals.
So, simply as we divide the given number by 10, the decimal point moves to the left making the value of whole number decreases and making the number of digits of decimal increase.
Answer:
y = 6
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 3 when x = 9, then
k =
=
=
, thus
y =
x ← equation of variation
When x = 18, then
y =
× 18 =
= 6
X=4 ........................................
