Question below. Please answer it, its math.

Answer 1

- 0.8

Explanation:

The first thing we want to do here is simplify the expression -

`(3)/(5)`( 2x + 5 ) - 2x, Distribute the "
`(3)/(5)` " to elements within the parenthesis

=
`(3)/(5)`
`*` 2x +
`(3)/(5)`
`*` 5 - 2x, Focus on simplifying the expression "
`(3)/(5)`
`*` 2x +
`(3)/(5)`
`*` 5 "

=
`2\cdot (3)/(5)x+5\cdot (3)/(5)` - 2x

=
`(6x)/(5)+3` - 2x, Combine fractions

=
`-(4x)/(5)` + 3

=
`-(4)/(5)`x + 3

So we have our simplified expression "
`-(4)/(5)`x + 3, " with
`-(4)/(5)` being the coefficient of x. Our requirements are that this fraction should be expressed as a decimal, so we can simply divide the numerator by the denominator to figure that out,

- 4 / 5 = - 0.8,

Solution = - 0.8
