Question

plzzz help me plzzzz​

Answer 1

Answer:

• 0.135bar  -  let x be 0.135 (equation 1)

                      100x - 13.5 ( equation 2 )

                     1000x -135.5 ( equation 3 )

               equation 3 -2

               1000x - 100x = 900x

                  135.5 - 13.5 = 112

              x  = $\frac{112}{900}[/tex = [tex]\frac{28}{225}$ ( if you reduce into lowest form )

• 2.045bar -  let x be 2.045 (equation 1)

                           100x - 204.5 bar ( equation 2)

                         1000x - 2045.5

                        equation 3 -2

                     1000x - 100x = 900x

                      2045.5 - 204.5 = 1841

                x =  $\frac{1841}{900\\}$

when you add these two  : 28/225 + 1841/900 = 2.17

NOTE : i am not sure abt the answer
