Question

0,4(x-7)+3,5-0,5(x+6)

Answer 1

Ответ:

$0.4x - 2.8 + 3.5 - 0.5x - 3 = - 0.1 - 2.3$

Answer 2

To simplify the expression, let's start by distributing the coefficients:

0.4(x - 7) + 3.5 - 0.5(x + 6)

0.4 * x - 0.4 * 7 + 3.5 - 0.5 * x - 0.5 * 6

Now, we can simplify further by combining like terms:

0.4x - 2.8 + 3.5 - 0.5x - 3

(0.4x - 0.5x) + (-2.8 + 3.5 - 3)

(-0.1x) + (-2.8 + 3.5 - 3)

Now, let's simplify the constants:

(-0.1x) + (-2.8 + 0.7 - 3)

(-0.1x) + (-2.8 - 2.3)

Now, combine the constants:

(-0.1x) + (-5.1)

Finally, we can write the simplified expression as:

-0.1x - 5.1
