Answer:
(12,3) and (20,5)
Step-by-step explanation:
When using the direct variation equation we can check these by division and we get .25 for the answer of both.
3/12 and 5/20
Answer:
the slope equals 2. otherwise known as the coefficient of x.
10
10
10
10
6
should be the answer
To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.
2/10 = x/5
Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:
(5)(2) = (10)(x)
Let's multiply out these numbers to further simplify the equation.
10 = 10x
Finally, we have to divide both sides by 10, to get our variable x alone
x = 1
Therefore, 2 tenths is equal to 1 fifth.
