17,6

Answer 2

Ответ:

17,6

Пошаговое объяснение:

8(0,5a+b) при a=2, b=1,2 то

8(0,5×2+1,2)=8×2,2=17,6

Answer 3

To simplify the expression 8(0.5a + b) with a = 2 and b = 1.2, we substitute the given values into the expression:

8(0.5a + b) = 8(0.5(2) + 1.2)

Simplifying further:

8(0.5(2) + 1.2) = 8(1 + 1.2)

Now, add the values inside the parentheses:

8(1 + 1.2) = 8(2.2)

Finally, multiply 8 by 2.2:

8(2.2) = 17.6

Therefore, the simplified expression 8(0.5a + b) with a = 2 and b = 1.2 is equal to 17.6.
