A = b - 2
a - 3b = 22
(b - 2) - 3b = 22
b - 2 - 3b = 22
-2 - 2b = 22
-2b = 24
-b = 12
b = -12
a = b - 2
a = -12 - 2
a = -14
Solution set {-14, -12}

Step-by-step explanation:
Answer:
11,400 ft^2
with no allowances for doors or windows
Step-by-step explanation:
ceiling: (35)(40) = 1400
walls: 2(35 x 16) + 2(40 x 16) = 2400
2400 = 1400 = 3800 ft^2
3800 ft^2 x 3 = 11,400 ft^2
199 is greater than 190, and less than 200.
Step-by-step Answer:
The coordinates of the mid-point of a segment whose end-points are known is the average of the coordinates of the end-points.
Here, the end-points are: (-11,0), (9,-1)
So the x-coordinate of the mid-point is (-11+9)/2 = (-2/2) = -1, and
the y-coordinate of the mid-point is (0-1)/2 = -0.5
So the mid-point is (-1,-0.5)
