1/4 .....divide the pizza by 4 ...so you get 1/4 ...taken by each friend !
He drove 140 miles you take 245 divide by 7 then times by 4
Answer: 
Step-by-step explanation:
A direct variation equation has the form:

Where <em>k</em> is a constant.
By definition, we know that the perimeter of the square is the sum of the lengths of its sides or, as all the sides are equal, you can multiply the lenght of any side by 4.
Then, knowing that <em>y</em> is the dependent value and <em>x</em> the independent value and the constant <em>k=4, </em> you can write the following direct variation equation that represents the situation.

Are there any answer choices ?
it means the distance around a two dimensional shape.
To find the perimeter, add all the side lengths
hope it helps!!!!!!!
