Question

3(x+1)- 2,4(x- 0,5)​

Answer 1

Ответ:

$3x + 3 - 2.4x + 1.2 = 0.6x + 4.2$

Если приравнять выражение 0 то

$0.6x + 4.2 = 0 \\ 0.6x = - 4.2 \\ x = - 7$

Answer 2

Ответ:

0,6x + 4,2

Пошаговое объяснение:

$3(x+1)-2.4(x-0.5)=3x+3-2.4x+1.2=0.6x+4.2$

Answer 3

To simplify the expression 3(x+1)- 2.4(x-0.5), let's start by applying the distributive property:

3(x+1) - 2.4(x-0.5) = 3x + 31 - 2.4x + 2.40.5 = 3x + 3 - 2.4x + 1.2

Next, combine like terms by adding or subtracting the coefficients of x:

(3x - 2.4x) + (3 + 1.2) = 0.6x + 4.2

Therefore, the simplified form of the expression 3(x+1)- 2.4(x-0.5) is 0.6x + 4.2.
