I pretty sure only 2,700 divides by 3 (the fourth one) would be right. When you remove a serious from one side of the equation, you have to remove one from the other side of the equation.
the complete question in the attached figure
step 1
Find the distance of the center of the wall from the left end of the wall
distance=(1/2)*24--------> 12 ft
so
If x is the distance from a painting edge to its corresponding end of the wall, then
|x-12| is the distance from the painting edge to the center of the wall
and
If the painting is centered, then 2|x-12| represents the width of the painting
Since the painting is 10 ft wide,
we have 2|x-12|=10
therefore
the answer is the option B
2|x-12|=10
X divided by 30 because it is going down by 30 percent.. :)
This is where Pythagorean's Theorem comes into play. a^2+b^2=c^2
So take 4^2 + 7^2 (which is 16+49), and your result is 65. Take the square root of 65 and you get 8.06 (8.1 rounded up)
