Question

8+2x деленное на 5≥1

Answer 1

5>=1 верно
(8+2х)/5=1,6+0,4х

Answer 2

To solve the inequality 8 + 2x divided by 5 ≥ 1, we'll follow these steps:

1. Subtract 8 from both sides of the inequality: (8 + 2x)/5 - 8 ≥ 1 - 8

Simplifying the equation: (8 + 2x)/5 - 8 ≥ -7

2. Simplify the left side of the inequality: [(8 + 2x) - 8 * 5]/5 ≥ -7

Simplifying further: (8 + 2x - 40)/5 ≥ -7 (2x - 32)/5 ≥ -7

3. Multiply both sides of the inequality by 5 to eliminate the fraction: 5 * (2x - 32)/5 ≥ -7 * 5

Simplifying: 2x - 32 ≥ -35

4. Add 32 to both sides of the inequality: 2x - 32 + 32 ≥ -35 + 32

Simplifying: 2x ≥ -3

5. Divide both sides of the inequality by 2 to solve for x: (2x)/2 ≥ -3/2

Simplifying: x ≥ -3/2

Therefore, the solution to the inequality 8 + 2x divided by 5 ≥ 1 is x ≥ -3/2.
