Which system is inconsistent and independent?

Consider the last set of equations:-

x - y - z = 2(1)

x + y - z = 3(2)

-x + y + z = 4(3)

Subtract:-  (2) - (1)       (x and z's disappear):-

2y = 1

y = 1/2

Now add:- (2) + (3):-

2y = 7

y = 3 1/2

Therefore this set is

inconsistent  and independent.

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
