So we should reverse the equation to
10+10=2x
We know that 10+10 is 20
and 20 divided by 2 is 10
so x=10
Your answer is 3. 3*2= 6 6-7= -1 and if -1 is increased by 2 you get 1. So the mystery number is 3 I hope this helps:)
N/-3>4-5
then you can just times by -3 to get n on it's own
n>-3(4-5)
n>-3*-1
n>3
The area of the actual castle would be 388,800 sq. ft.
We would multiply each of the sides of the scale model both by 180 to find the side lengths of the actual castle.
So...
180 x 4 = 720
180 x 3 = 540
If Area is equal to Length Times Width, all thats left to do is to multiply the two sides together.
720 x 540 = 388,800
Hope this helped! :D
