x= the cost of each meter. Simplify that and you will get $0.8 m\
now convert it to mm.
$0.8m x 1m/ 1000mm which equals 0.0008.

Solve the following...<br>6x - 5 = -9x -9​
sergiy2304 [10]

\quad \huge \quad \quad \boxed{ \tt \:Answer }

[ add 9x and 5 on both sides ]

\qquad \tt \rightarrow \: 6x - 5 + 9x + 5 =  - 9x - 9 + 9x + 5

\qquad \tt \rightarrow \: 6x + 9x =  - 9 + 5

\qquad \tt \rightarrow \: 15x = -  4

\qquad \tt \rightarrow \: x =  -  \cfrac{4}{15}
