Answer:
C. x is y less than z
Step-by-step explanation:
x+y=z
by using transposition
x = z-y
whatever x is, it is equal to the value of y taken from z

Let p represent # of physics texts sold
Let m represent # of maths texts sold
Therefore we have p = m - 60 | because physics texts sold are less than maths by 60
Total sold = 206 = m + p | recall that p = m - 60
We then have 206 = m + m - 60
206 = 2m - 60 | adding 60 to both sides, we have
206 + 60 = 2m | dividing both sides by 2
266/2 = 2m/2
Therefore, m = 133 texts
and p = m - 60 = 133 - 60 = 193
Side of base of square, a = 10 km.
Height of pyramid , h = 12 km.
Volume of pyramid is given by :
Surface area is given by :
Therefore, volume and surface area are 400 km³ and 340 km² respectively.
Hence, this is the required solution.
