Which property is used when you write 3(x + 4) = 3x + 12?
Answer: Distributive Property
The Distributive Property states a(b + c) = ab + ac, so 3(x + 4) = 3x + 12.
A vending machine charges $1.25 per snack. Which expression shows the cost of s snacks?
Answer: 1.25s
Multiplying the price per snack by the number of snacks gives 1.25s.
Solve for y: y/4 = 9
Answer: 36
Multiplying both sides by 4 gives y = 36.
A sequence starts at 80 and decreases by 7 each step. What is the 5th term?
Answer: 52
Starting at 80 and subtracting 7 four times: 80, 73, 66, 59, 52.
Which situation can be modeled by the equation 15 + x = 40?
Answer: You have 15 stickers and need to reach 40 total.
Starting with 15 and adding x more to reach 40 is written as 15 + x = 40.
What is the missing value in the table? x: 2, 4, 6, 8 | y: 10, 20, __, 40
Answer: 30
The rule is y = 5x; when x = 6, y = 5(6) = 30.
Which expression is equivalent to 6m + 9?
Answer: 3(2m + 3)
Factoring out 3 gives 3(2m + 3) = 6m + 9.
