Question

(0.8х+19.4)помножити 0.2=1.928

Answer 1

1.928/0.2=9.64
9.64-19.4=-9.76
-9.76/0.8=-12.2

Answer 2

The equation you provided is:

(0.8x + 19.4) * 0.2 = 1.928

To solve this equation, we can start by distributing the 0.2 to each term inside the parentheses:

0.2 * 0.8x + 0.2 * 19.4 = 1.928

0.16x + 3.88 = 1.928

Next, we can subtract 3.88 from both sides of the equation to isolate the term with x:

0.16x = 1.928 - 3.88

0.16x = -1.952

Finally, we divide both sides of the equation by 0.16 to solve for x:

x = -1.952 / 0.16

x ≈ -12.2

Therefore, the solution to the equation is x ≈ -12.2.
