3*0,3*(-0,8)-5*(-0,8)=3,28

Answer 2

To evaluate the expression (3x-5)*y with x = 0.3 and y = -0.8, we substitute the given values into the expression and perform the calculations.

(3(0.3) - 5) * (-0.8)

First, let's simplify the expression inside the parentheses:

= (0.9 - 5) * (-0.8)

= (-4.1) * (-0.8)

Now, multiply -4.1 by -0.8:

= 3.28

Therefore, when x = 0.3 and y = -0.8, the value of the expression (3x-5)*y is 3.28.
