We can chang efractions to compare them by multiplying them by 1 or x/x where x=x so

1/2=7/12?
make bottom numbers equal
2 times what=12
divide 2
what=6

1/2 times 6/6=6/12
6/12=7/12
6=7
false

so therefor it does NOT equal 7/12

Variable y varies directly with variable x. If x = 12, then y = 3. What is the value of y

Monica [59]

Answer:

Step-by-step explanation:

To find the value of y when x = 8 we must first find the relationship between the two variables.

The statement

y varies directly with variable x is written as

y = kx

where k is the constant of proportionality

when

x = 12

y = 3

Substitute the values into the above formula and solve for k

That's

3 = 12k

Divide both sides by 12

$k = \frac{1}{4}$

So the formula for the variation is

$y = \frac{1}{4} x$

when

x = 8

$y = \frac{1}{4} \times 8$

we have the final answer as

Hope this helps you
