Answer:
x = c - b
Step-by-step explanation:
c = x + b
Subtract b on both sides,
c - b = x + b - b
c - b = x
x = c - b
Hence, solved.
Answer:
16.5 ft by 25.5 ft
Step-by-step explanation:
Let w represent the width of the garden in feet. Then w+9 is the garden's length, and w(w+9) represents its area.
The surrounding walkway adds 8 feet to each dimension, so the total area of the garden with the walkway is ...
(w+8)(w+9+8) = w^2 +25w +136
If we subtract the area of the garden itself, then the remaining area is that of the walkway:
(w^2 +25w +136) - (w(w+9)) = 400
16w + 136 = 400 . . .simplify
16w = 264 . . . . . . . . subtract 136
264/16 = w = 16.5 . . . . . width of the garden in feet
w+9 = 25.5 . . . . . . . . . . .length of the garden in feet
The tenths place, starting from the right, it gets higher going to the left. so the tenths place is only ten times greater than it.
Fractional form: 63/10 or 6 3/10.
That means the decimal is repeatative
