Distribution and Solve

Solve for x using distribution:

–2(x+5) = 8

Solve for x. Distribute then Combine Like Terms: 3(2x – 5) – 4x = –19

• x = –2

• x = 2

• x = 10

• x = –11

Solve for x. Distribute then Combine Like Terms:

–4 (3x – 7) = 4

When distributing a number through ( ), it needs to multiply to __________________

• just the first term inside the ( )

• just the last term inside the ( )

• every term inside the ( )

• any two terms inside the ( )

How is the data distributed in this histogram?

• Symmetrically

• Skewed Right

• Skewed Left

The following table represents the probability distribution X, the employment status of adults in a city. What is the probability that the adults isn't retired?

The following table represents the probability distribution X, the employment status of adults in a city.

What is the probability that the adults isn't retired?

• add the 5
  

• divide by the 2
  

• distribute the 3
  

• subtract the 21
  

Solve the equation below:

3 (2x + 3) = 21

Solve the equation below. Distribute FIRST and then combine like terms:

3 (4 – 2x) + 4x = 2

• x = 5

• x = 1

• x = –1

• x = –5
