Thank you!

1) is this one the Moon? not very sure..

2) I do not know this one

3) I think that this is a trick question...isn't the color of yolk yellow?

5x - 8 = 5 + 4x - 12

Step 1) Group the like terms.

5x - 4x = 5 - 12 + 8

Step 2) Add/Subtract the like terms.

x = 1 

Volume of a pyramid = 1/3 x Area of base x height
= 1/3 x 900 x 40
= 12000 cm^3 

Volume of tank = length x breadth x height
= 40 x 40 x 40
= 64000 cm^3 
64000 - 12000 = 52000 cm^3 water left 
52000 cm^3 / 40 x 40 = h
h = 32.5cm

So, the depth of water in the tank is 32.5 cm. Hopefully that helped!

Thank you!!! This really helped me!
