<span>22.5+7 (n-3.4)=19.8n

We simplify the equation to the form, which is simple to understand
<span>22.5+7(n-3.4)=19.8n

Reorder the terms in parentheses
<span>22.5+(+7n-23.8)=19.8n

Remove unnecessary parentheses
<span>+22.5+7n-23.8=+19.8n

We move all terms containing n to the left and all other terms to the right.
<span>+7n-19.8n=-22.5+23.8

We simplify left and right side of the equation.
<span><span>-12.8n=+1.3

</span>We divide both sides of the equation by -12.8 to get n.
<span>n=-0.1015625</span></span></span></span></span></span></span>

Rectangle PQRS is rotated 90 counterclockwise about the origin what are the coordinates of point Q
inna [77]
You have not provided the diagram/coordinates for point Q, therefore, I cannot provide an exact answer.
However, I can help you with the concept.

When rotating a point 90° counter clock-wise, the following happens:
coordinates of the original point: (x,y)
coordinates of the image point: (-y,x)

Examples:
point (2,5) when rotated 90° counter clock-wise, the coordinates of the image would be (-5,2)

point (1,9) when rotated 90° counter clock-wise, the coordinates of the image would be (-9,1)

point (7,4) when rotated 90° counter clock-wise, the coordinates of the image would be (-4,7)

Therefore, for the given point Q, all you have to do to get the coordinates of the image is apply the transformation:
(x,y) .............> are changed into.............> (-y,x)

Hope this helps :)
