Question

Urgent please help!!!!

Answer 1

Explanation:

Inequality given for Sara,

-4(2x + 4) > 8x + 64

-8x - 16 > 8x + 64

-8x - 8x > 16 + 64

-16x > 80

-x > 5

x < -5

x = -12 will be the answer.

Option (3)

Inequality for Alezandro,

7x + 20 ≥ 2(x - 15)

7x + 20 ≥ 2x - 30

7x - 2x ≥ -30 - 20

5x ≥ -50

x ≥ -10

Therefore, x = 2 is the answer.

Option (2)

For Daria,

3(x - 17) < 9(1 - 3x)

3x - 51 < 9 - 27x

3x + 27x < 51 + 9

30x < 60

x < 2

x = -6 will be the answer.

Option (1)

For Jamal,

5(x + 11) > -4(-x - 12)

5x + 55 > 4x + 48

5x - 4x > 48 - 55

x > -7

x = 10 will be the answer.

Option (4)
