Sarah describes the following situation: When fertilizer was added to one plant and nothing was added to the other plant, there

was a noticeable difference in the color of the leaves of the plants.
Which of the following best describes the situation?
(a)this an example of correlation, because the fertilizer causes the plant to change color
(b)this is an example of causation, because the aplication of fertilizer caused the plant to improve its leaf color
(c)this is an example of correlation, because one plant is being fertilized and the other is not
(d)this is an example of causation, because the leaves on both plants change color

A) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number. 
\frac{27}{45} = \frac{x}{5}

Next, you would cross multiply. 
135 = 45x

Now, the last step would be to isolate the x. To do this, you would divide both sides by 45. 
3 = x

\frac{27}{45} = \frac{3}{5}

b) To solve this equation, you would need to fill in the blank with a substitute. Let x represent the unknown number. 
\frac{2}{6} = \frac{3}{x}
Next, you would cross multiply. 
18 = 2x

Now, the last step would be to isolate the x. To do this, you would divide both sides by 2. 
9 = x

\frac{2}{6} =\frac{3}{9}

I hope this helps!

1) RED will be rotated 90° counterclockwise around the origin.

2) The coordinates of R'E'D' will be R'(2, 2); E'(0, 4) and F'(0, 0).  The rule for a 90° counterclockwise rotation about the origin is that the coordinates (x, y) are mapped to (-y, x).

3) An isometric transformation is one in which the angles between sides and the distances of each side are preserved between the pre-image and the image.  This means the angle measures and side lengths will be the same.  Therefore the image will be similar to the pre-image, as the angle measures will be the same and the side lengths will be proportional.

Which equation can you use to solve for x? x + 56 = 180 x + 146 = 180 180−x=146 x + 56 = 146 The figure contains a pair intersec
Harlamova29_29 [7]
The correct question is
<span>Which equation can you use to solve for x? x + 56 = 180 x + 146 = 180 180−x=146 x + 56 = 146 The figure contains a pair intersecting lines. One of the four angles formed by the intersecting lines is labeled 146 degrees. The angle opposite and not adjacent to this angle is broken into two smaller angles by a ray that extends from the point where the two lines intersect. One of these smaller angles is labeled 56 degrees, and the other smaller angle is labeled x degrees.

see the picture attached to better understand the problem

we know that
angle 146</span>° and angle (56°+x°) area equal -----> by vertical angles
so
146=56+x
therefore

the answer is
<span>x + 56 = 146</span>
