Question

-3(8,2y-7)+4,6y если y=1,6

Answer 1

Ответ будет такой -11,32

Answer 2

To evaluate the expression, we substitute y=1.6 into the given expression and simplify using the order of operations (PEMDAS):

-3(8,2y-7)+4,6y = -3(8,2(1.6)-7)+4,6(1.6) (Substitute y=1.6) = -3(8.2-7)+7.36 = -3(1.2)+7.36 = -3.6+7.36 = 3.76

Therefore, the value of the expression when y=1.6 is 3.76.
