(A) 2/3A= -24
A= -24 • 2/3
A= 48/3
A= 16
(B) 20= -B/0.2
20 • 0.2= -B
4= -B
-4= B
(C) Distance between Point A & Point B is 20
Area of the room = 14*15 = 210 ft^2
Cost padding = 210*89 = 186.90
Cost of carpet = 210 * 2.99 = 627.90
Perimeter of the room = 2*15 + 2*14 = 58 ft
Cost of strip = 58*0.19 = 11.02
Total cost of supplies = 186.90 + 627.90 + 11.02 = 825.82 Answer
Remember you can do anything to an equation as long as you do it to both sides
(y/4)-49=-9
isolate the variable
add 49 to both sides
y/4=40
multiply both sides by 4 to clear fraction
y=160
D is the answer. Hope this helps!
