Answer 1

Ответ:

-7

Пошаговое объяснение:

3*-8=-24

-24-9=-33

1/3*-33=-11

-11+-4=-7

Answer 2

To find the value of the expression 1/3 • (3a - 9) + b when a = -8 and b = -4, we substitute the given values into the expression and perform the calculations.

1/3 • (3(-8) - 9) + (-4)

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

1/3 • (-24 - 9) + (-4)

Next, calculate the subtraction within the parentheses:

1/3 • (-33) + (-4)

Now, multiply 1/3 by -33:

(-33/3) + (-4)

Simplify the division:

-11 + (-4)

Finally, perform the addition:

-15

Therefore, the value of the expression 1/3 • (3a - 9) + b when a = -8 and b = -4 is -15.
