The horizontal position for the left edge of the image which Joelle should use to center the image = -4.46cm
We have been told that in the question that the horizontal positions to the right of the leftmost edge of the page are positive.
Given
Joelle is working on a school report on a word processor.
She wants to place an oversized image that is 30.51 cm wide so that it appears centered on the page.
The width of the page is 21.59 cm.
Width of the oversized image = 30.51cm
The first step is to subtract the width of the word processor page from the width of the oversized image.
30.51cm - 21.59cm
8.92cm is the space left
Since we have two sides, horizontal positions to the leftmost side and horizontal positions to the right of the leftmost edge of the page.
The next step is we divide 8.92 by 2
= 8.92cm ÷ 2
= 4.46cm
Automatically, the horizontal position for the left edge of the image which Joelle should use to center the image would the negative.
Therefore, horizontal position for the left edge of the image which Joelle should use to center the image = -4.46cm
