Solve the equation <br> 14(3x-1)=2x-23
irina1246 [14]

Answer:

x=\frac{-9}{40} \\

Step-by-step explanation:

Given Equation:

           14(3x-1)=2x-23

Solving the bracket on L.H.S

        (14)(3x)-1(14)=2x-23

             42x-14=2x-23

Taking the terms of 'x' to one side and the constants to other side

                 42x-2x=-23+14\\\\40x=-9\\\\x=\frac{-9}{40} \\

The value of 'x' after solving the equation is:

                            x=\frac{-9}{40} \\

Find the volume of this square<br> based pyramid.<br> 10 cm<br> 8 cm<br> 8 cm<br> V = [?] cm3
oksano4ka [1.4K]

Answer:

213.3

Step-by-step explanation:

The volume of a pyramid is 1/3 base times height.

Using this formula, our square base is 8*8, or 64 square units.

Multiplying that by the height, 10. We get 64*10, 640.

Finally dividing by 3, we have 213.3333333333...

Rounding that to the nearest tenth, 213.3.
