Question

1)6а-17а+19а-8а 2)у+0,65у+(-2,75)+(-0,65х)-х

Answer 1

Ответ:

• 0
• 0,55 (3у - 5 - 3х)

Пошаговое объяснение:

1. 6а - 17а + 19а - 8а = 0
2. у + 0,65у + (-2,75) + (-0,65х) - х = 1,65у - 2,75 -1,65х = 0,55 (3у - 5 - 3х)

Answer 2

It looks like you have two mathematical expressions that involve variables. Let's simplify each expression:

1. 6a - 17a + 19a - 8a

To simplify this expression, you can combine like terms. Like terms have the same variable (in this case, "a") raised to the same exponent. Here, all the terms have "a" raised to the first power.

6a - 17a + 19a - 8a = (6 - 17 + 19 - 8)a

Now, perform the arithmetic operations inside the parentheses:

(6 - 17 + 19 - 8) = 0

So, the simplified expression is:

0a, which is just 0.

2. y + 0.65y - 2.75 - 0.65x - x

Similarly, let's simplify this expression by combining like terms:

y + 0.65y - 2.75 - 0.65x - x = (1 + 0.65)y - 2.75 - 0.65x - x

Now, perform the arithmetic operations inside the parentheses:

(1 + 0.65)y = 1.65y

So, the expression becomes:

1.65y - 2.75 - 0.65x - x

Now, let's simplify the constants:

-2.75 - 0.65x - x = (-2.75 - x - 0.65x)

Now, combine like terms by adding the coefficients of x:

(-1 - 0.65)x = -1.65x

So, the simplified expression is:

1.65y - 1.65x - 2.75
