Aliun [14]

Answer:

14 : 21

Step-by-step explanation:

---> 2:3 ----> 2+3=5

---> Stick's length = 35 inches

<u>For the second portion</u>

3/5 x 35

Algebra II<br> line: 3(x - 2) > 5x + 8

m_a_m_a [10]

Answer:

x < - 7

Step-by-step explanation:

Given

3(x - 2) > 5x + 8 ← distribute parenthesis on left side

3x - 6 > 5x + 8 ( subtract 3x from both sides )

- 6 > 2x + 8 ( subtract 8 from both sides )

- 14 > 2x ( divide both sides by 2 )

- 7 > x, hence

x < - 7
