Rewrite the fractions with the same LCD.
pantera1 [17]

4 = 2*2

6 = 2*3

9 = 3*3

LCD = 2 * 3* 2 * 3 = 36

so the fractions are 3/4 * 9/9 = 27/36

5/6 = 30/36 and 5/9 = 20/36

Identify as a direct variation, inverse variation or neither. The number of tons of coal burned by an old coal burning locomotiv
pochemuha
Answer: it is a direct variation.

Justification:

In a direct variation the variables are related by a proportionality constant in this way:

y = k x

Tthan means that the value of y is always the product of a constant times the value of x.

The situation discribed for the coal may be written as:
number of tons of coal burned: c

number of hours: h

⇒ c = k × h

Which is that you can calcualte the number of tons of coal burned at any time, once you know the proportionality constant k.
