Answer:
Volume of a brick = 0.00975 m³.
Step-by-step explanation:
Volume of the wall = 63 m³
Cost to build the wall = 84000 Rs
Cost to prepare a brick = 13 Rs
Since, relation between cost of the wall is directly proportional to the volume of the wall
C ∝ V
C = kV
Here, k = Proportionality constant
k = = Constant
Therefore,
V₂ =
= 0.00975 m³
Therefore, volume of a brick is 0.00975 m³.

Answer:
Infinitely many solutions
Step-by-step explanation:
2y=14-2x
y=-x+7
------------
2(-x+7)=14-2x
-2x+14=14-2x
-2x-(-2x)=14-14
-2x+2x=0
0=0
infinitely many solutions
