Apparently you had to scooty out of here before you had a chance to
tell us what the choices are.  So there's no way for anybody to help you
find the correct ones.

For an equation to show direct variation:

-- When either 'x' or 'y' is zero, the other one must be zero too.

-- 'x' and 'y' must both be to the first power in the equation. 
     What I mean is;  no squares or higher powers of 'x' or 'y',
     no square roots, or cubes etc.

and

-- If 'x' or 'y' is in the denominator of a fraction,
then it has to be in the numerator too.

Answer:

The perimeter is 22.

Step-by-step explanation:

If you turn this shape into a rectangle, the perimeter doesn't change.

The width is given, it is 7.5. The height is BC+DE = 3.5

Then the perimeter is twice the width plus twice the height:

7.5*2 + 3.5*2 = 15+7 = 22

(1) The ratios 18:3 and 6:1 are equivalent. Why?
aliya0001 [1]

Answer:

Because if you take 18:3 and divide both sides by 3, you will get 6:1

Step-by-step explanation:

Because 18:3 divided by 3 on both sides equals 6:1, also 6:1 times 3 on both sides equals 18:3.
