Answer: -8 is the answer.
Step-by-step explanation:
according to the question:
{{(8+4)*5}/(-10)}-2
= {[12*5}/(-10)]-2
= [60/(-10)]-2
= -6-2 = -8
Will its 12.75 because you add 3+9 =12 and you just put the 75 that's it
X=2
Y=4
Multiply top so y values cancel out, so multiple top by -3. Y values cancel out. You combine top and bottom equations, x=2. Plug 2 in first equation for x. Y=4
Area is the length times the width.
When you know the area and one of the dimensions, divide the area by the known dimension to find the other one.
133 / 11 = 12.09
The room needs to be at least 12.09 feet wide. ( round answer if needed).
