Question

5g +2 r при g=-4,5r=-1,6

Answer 1

5•(-4,5)=-22,5
2•(-1,6)=-3,2
-22,5+(-3,2)=-25,7

Answer 2

To evaluate the expression 5g + 2r with the given values g = -4 and r = -1.6, substitute these values into the expression:

5g + 2r = 5(-4) + 2(-1.6)

Now calculate:

= -20 + (-3.2) = -20 - 3.2 = -23.2

Therefore, when g = -4 and r = -1.6, the value of the expression 5g + 2r is -23.2.
