The required simplified expression for 0.2(5x – 0.3) – 0.5(–1.1x + 4.2) is 1.55x - 2.16.
What is simplification ?
Simplification means reducing the expression in a simpler form using various operations. It eliminates unnecessary diversiry and variety.
The given expression is
0.2(5x – 0.3) – 0.5(–1.1x + 4.2)
or, 0.2 [5x + (–0.3)] + (–0.5)(–1.1x + 4.2) x – 2.16
Now,Let us expand the bracket-
0.2*5x - 0.2*0.3 - 0.5(-1.1x) - 0.5*4.2
Further,
x - 0.06 + 0.55x - 2.1
therefore,
x + 0.55x - 0.06 - 2.1
⇒ 1.55x - 2.16
Hence,the required simplified expression for 0.2(5x – 0.3) – 0.5(–1.1x + 4.2) is 1.55x - 2.16.
