Question

7.7x-3.6x-0.1x при x=5.13

Answer 1

$7.7x - 3.6x -0.1x = 4x = 4 \times 5.13 = 20.52$

Answer 2

To evaluate the expression 7.7x - 3.6x - 0.1x when x = 5.13, simply substitute the value of x into the expression and perform the arithmetic:

7.7x - 3.6x - 0.1x = (7.7 - 3.6 - 0.1) * x

Now, plug in x = 5.13:

= (7.7 - 3.6 - 0.1) * 5.13 = (4.0) * 5.13 = 20.52

So, when x = 5.13, the value of the expression 7.7x - 3.6x - 0.1x is 20.52.
