Answer:
no, y does not vary directly with x
Step-by-step explanation:
If there is direct variation, the constant of variation can be found as ...
k = y/x
Here, those ratios are ...
y/x = 6/3 = 2
y/x = 18/6 = 3
y/x = 24/8 = 3
The ratio of y to x is NOT A CONSTANT, so <em>there is no direct variation.</em>
Answer:
Width = 66 inches
Step-by-step explanation:
Zelda has 300 inch roll of binding for a quilt.
The length must be 84 inches
We need to find its width. Let it is b.
Let us assume that the quilt is in the shape of rectangle. The perimeter of the rectangle is given by :
P = 2(l+b)
300 = 2(84+b)
150 = 84+b
b = 150-84
b = 66 inches
So, the required width is 66 inches.
Answer:

Step-by-step explanation:
T = 2
1. Divide both sides by 2
--> t / 2
=
2. Square both sides
-->
/ 4
= m / k
3. Multiply both sides by k
--> m = k
/ 4
