Ответ:- 6,4 - 0,1у

Пошаговое объяснение:

0,3*(8-3у)-3,2+0,8*(у-7) = 2,4 - 0,9у - 3,2 + 0,8у - 5,6= - 6,4 - 0,1у

Answer 3

To simplify the expression, follow the order of operations (PEMDAS):

P - Parentheses E - Exponents MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

The given expression is: 0.3*(8 - 3y) - 3.2 + 0.8*(y - 7)

Step 1: Simplify within the parentheses 8 - 3y = 8 - 3y

y - 7 = y - 7

Step 2: Perform the multiplications 0.3*(8 - 3y) = 0.3 * 8 - 0.3 * 3y = 2.4 - 0.9y

0.8*(y - 7) = 0.8 * y - 0.8 * 7 = 0.8y - 5.6

Step 3: Combine like terms The expression now becomes: (2.4 - 0.9y) - 3.2 + (0.8y - 5.6)

Step 4: Perform the additions and subtractions (2.4 - 0.9y) - 3.2 = -0.8 - 0.9y

-0.8 - 0.9y + 0.8y - 5.6

Step 5: Combine like terms again -0.8y - 6.4

So the simplified expression is: -0.8y - 6.4
