Question

InequaçãoOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Answer 1

a)

x/3 ≤ 1/4 + (3x - 2)/5

20x ≤ 15 + 12(3x - 2)

20x ≤ 15 + 36x - 24

9 ≤ 36x - 20x

9 ≤ 16x

9/16 ≤ x

b)

5(x - 3) + 5x > 3(x - 10)

5x - 15 + 5x > 3x - 30

10x - 3x > 15 - 30

7x > - 15

x > - 15/7

c)

x/3 - 5/2 + x < - 2

2x - 15 + 6x < - 12

8x < 15 - 12

8x < 3

x < 3/8

d)

(1 + 2x)/2 - 3 > 2/3 - 3(x - 2)/2

3(2x + 1) - 18 > 4 - 9(x - 2)

6x + 3 - 18 > 4 - 9x + 18

6x + 9x > 22 + 15

15x > 37

x > 37/15

Resposta:

a) 9/16 ≤ x

b) x > - 15/7

c) x < 3/8

d) x > 37/15
