Answer 1

Ответ:

Пошаговое объяснение:

5* (2,3х + 4,1 у) + 3*(1,3 х + 4,2у)=

11,5х+20,5у+3,9х+12,6у=15,4х+33,1у

15,4*0,1+33,1*0,2=1,54+6,62=8,16

Answer 2

To evaluate the expression 5*(2.3x + 4.1y) + 3*(1.3x + 4.2y) with x = 0.1 and y = 0.2, we substitute the given values into the expression and perform the calculations.

Replacing x with 0.1 and y with 0.2, we have:

5*(2.30.1 + 4.10.2) + 3*(1.30.1 + 4.20.2)

Simplifying further:

5*(0.23 + 0.82) + 3*(0.13 + 0.84)

5*(1.05) + 3*(0.97)

5.25 + 2.91

The final result is:

8.16
