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
the answer is 470
Step-by-step explanation:Because 470+470 which equals 940 and the square root is 30
When multiplying by multiples of 10, move the decimal place one place over to the right. 44,000 becomes 440,000.
