Question

(0,4x-4,97)*0,55=0,8085

Answer 1

(0,4х-4,97)*0,55=0,8085
0,4х-4,97=0,8085:0,55
0,4х-4,97=1,47
0,4х=1,47+4,97
0,4х=6,44
х=6,44:0,4
х=16,1

Удачи:)
(0.4х-4.97)*0.55=0.8085 0.22х-2..7335=0.8085 0.22х=0.8085+2.7335 0.22х=3.542 Х=3.542:0.22 Х=16.1

Answer 3

Let's solve the equation step by step:

(0.4x - 4.97) * 0.55 = 0.8085

First, distribute the 0.55 into the parentheses:

0.55 * 0.4x - 0.55 * 4.97 = 0.8085

Now, simplify:

0.22x - 2.7335 = 0.8085

Next, isolate the variable (x) by moving the constant term (-2.7335) to the other side of the equation:

0.22x = 0.8085 + 2.7335 0.22x = 3.542

Finally, solve for x:

x = 3.542 / 0.22 x = 16.1

So, the value of x that satisfies the equation is approximately 16.1.
