Answer:

y = 6 when x = 18

Step-by-step explanation:

The appropriate formula for this direct proportion is y = kx, where k is the constant of proportionality.

We know y = 3 when x = 9: 3 = k(9)

This yields k = 3/9, or k = 1/3

Then the formula is y = (1/3)x

and when x = 18, y = (1/3)(18) = 6

y = 6 when x = 18

Draw Conclusions The decimal 0.3 represents What type of number best describes 0.9, which is 3.0.3? Explain

Anon25 [30]

Answer:

The product represent the number $3\times 0.3=0.9$

Step-by-step explanation:

To find : The decimal 0.3 represents What type of number best describes 0.9, which is 3.0.3?

Solution :

0.3 represents $0.3=\frac{3}{10}$

0.9 represents $0.9=\frac{9}{10}$

If we multiply 0.3 by 3 we get 0.9

As, $3\times 0.3=3\times \frac{3}{10}$

$3\times 0.3=\frac{9}{10}$

$3\times 0.3=0.9$

Therefore, The product represent the number $3\times 0.3=0.9$
