Step-by-step explanation:
When w=10, 7w=7×10=70
But the given value of 7w is 73.
So, the given value is not a solution of the equation.
Answer: T = 120 + .15*x
Let T be the total price
Let 'I' be the initial price
Let 'x' be the total number of vertical meters
So, T = I + .15*x
Putting T = 645 and x = 3500 in above equation
we get, I = 120
So, the required equation is
T = 120 + .15*x
(Volume for a rectangular shape is length x width x height)
We can split up this 3D composite figure into two main parts (as shown in the picture I attached), and find each part’s volume before adding them together for the total volume.
Cube —> 5x5x5 —> 25x5 = 125 in^3
Rectangular Prism —> 20x5x5 —> 100x5 = 500 in^3
125 + 500 = 625
So the answer is A. 625 in^3
