Answer 1

Ответ:

Здесь можно только сократить:

$0.8 \times (7 - 0.5x) - 0.2 \times (28 + 4x) = 5.6 - 0.4x - 5.6 - 0.8x = - 1.2x$

Answer 2

Ответ:

0,8•(7-0,5х)-0,2•(28+4х)=5,6-0,4х-5,6-0,8х=-0,4х-0,8х=-1,2х

Answer 3

To simplify the expression, let's begin by distributing the numbers and variables. Here's the step-by-step process:

0.8 * (7 - 0.5x) - 0.2 * (28 + 4x)

Step 1: Distribute the numbers in the first bracket:

= 0.8 * 7 - 0.8 * 0.5x - 0.2 * (28 + 4x)

Step 2: Simplify the terms:

= 5.6 - 0.4x - 5.6 - 0.8x

Step 3: Combine the like terms:

= (-0.4x - 0.8x) + (5.6 - 5.6)

= -1.2x + 0

= -1.2x

So, the simplified form of the expression is -1.2x.
