Distributing, Like terms, percents

Tomorrow is your math interim. You will have

• Distributing

• Combining like terms

• Finding a percent

• Finding a unit rate

Distribute is

• 2 (4 + x)

• You multiply the number outside the parenthesis with the numbers inside

• So you do 2 x 4 = 8

• Then 2 x X = 2x

• You keep the addition sign

• so your answer in 8 + 2x

Multiple Choice

What does distribute mean?

• Multiply a number outside of the parentheses with the numbers inside

• Add a number outside of the parentheses with the numbers inside

What does combine like terms mean?

• Adding, subtracting, multiplying, or dividing the numbers or letters that are the same

• So 4x + 8x can be combined

• 4x + 8x + 12x

• 3x + 1 / 4y can not be combined

• 3x, 1, and 4y are all the same so you can't simplify the answer

• 
  

Multiple Choice

Can you combine 3x + 5y + 4x

• yes

• no

Multiple Choice
