Which value of n makes 2n + 7 > 19 true?
Answer: 7
Solving: 2n > 12, so n > 6; the smallest whole number greater than 6 among the choices is 7.
A store sells notebooks in packs of 6. If the school needs at least 50 notebooks, what is the fewest packs it must buy?
Answer: 9
50 ÷ 6 ≈ 8.33, so the school must buy at least 9 packs to have enough.
Evaluate 4a − b when a = 5 and b = 8.
Answer: 12
4(5) − 8 = 20 − 8 = 12.
A gym charges $30 to join and $15 per month. Which expression gives the total cost after m months?
Answer: 15m + 30
The one-time fee is 30 and the recurring monthly fee is 15m, giving 15m + 30.
Which pair of expressions is equivalent?
Answer: 3(x + 2) and 3x + 6
Distributing gives 3(x + 2) = 3x + 6, which is equivalent.
In a pattern, the number of dots in figure n is given by 2n + 3. How many dots are in figure 6?
Answer: 15
2(6) + 3 = 12 + 3 = 15.
Which statement correctly describes what happens to y when x increases by 1 in the rule y = 5x − 2?
Answer: y increases by 5
The coefficient of x is 5, so each 1-unit increase in x causes y to increase by 5.
