Question

3,2(2x-4)+3,1x>1.5(4+3x)​

Answer 1

Ответ:

Х>3,76

Пошаговое объяснение:

3,2(2х-4)+3,1х>1,5(4+3х)

6,4х-12,8+3,1х>6+4,5х

9,5х-12,8>6+4,5х

9,5х-4,5х>6+12,8

5х>18,8

Х>3,76

Answer 2

To solve the inequality 3.2(2x - 4) + 3.1x > 1.5(4 + 3x), we will simplify the expression and find the value of x that satisfies the inequality.

Let's start by distributing the coefficients:

6.4x - 12.8 + 3.1x > 6 + 4.5x

Combine like terms:

9.5x - 12.8 > 6 + 4.5x

Now, let's isolate the x term on one side of the inequality:

9.5x - 4.5x > 6 + 12.8

Simplifying further:

5x > 18.8

Finally, divide both sides of the inequality by 5 to solve for x:

x > 18.8/5

Simplifying the division:

x > 3.76

Therefore, the solution to the inequality 3.2(2x - 4) + 3.1x > 1.5(4 + 3x) is x > 3.76.
