Question

6х-8y, если х= 2/5, 5/8

Answer 1

6•0.4(потому что мы переводимое в десятичные)-8•0.625
0.24-0.5=0.19
как то так

Answer 2

To find the value of the expression 6x - 8y when x = 2/5 and x = 5/8, we need to substitute these values into the expression and perform the calculations.

Let's start by evaluating the expression when x = 2/5:

6 * (2/5) - 8y

Now, let's evaluate the expression when x = 5/8:

6 * (5/8) - 8y

We don't have a specific value for y, so we can't determine the exact numerical result of the expression without knowing the value of y. If you have a value for y, you can substitute it in the above expressions to find the result. Otherwise, the result will be in terms of y.
