Q. Last week, Chichi spent 66 more hours practicing guitar than Will did. If Chichi practiced for 1414 hours last week, which of the following can be used to calculate x x , the number of hours Will practiced guitar last week?\newlineChoose 11 answer:\newline(A) x6=14 x-6=14 \newline(B) x+6=14 x+6=14 \newline(C) 6x=14 6 x=14 \newline(D) 14x=6 14 x=6
  1. Understand Relationship: Understand the relationship between the hours Chichi and Will practiced. Chichi practiced 66 more hours than Will. If we let xx represent the number of hours Will practiced, then Chichi practiced x+6x + 6 hours.
  2. Set Up Equation: Set up the equation using the information given.\newlineWe know that Chichi practiced for 1414 hours last week. Since Chichi practiced 66 more hours than Will, we can write the equation as x+6=14x + 6 = 14.
  3. Check Answer Options: Check the answer options against the equation.\newlineWe need to find the option that matches the equation x+6=14x + 6 = 14.\newlineOption (A) is x6=14x - 6 = 14, which does not match our equation.\newlineOption (B) is x+6=14x + 6 = 14, which matches our equation.\newlineOption (C) is 6x=146x = 14, which does not represent the relationship correctly.\newlineOption (D) is 14×x=614 \times x = 6, which is not a valid equation for this context.
  4. Choose Correct Answer: Choose the correct answer.\newlineThe correct answer is (B) x+6=14x + 6 = 14, as it represents the situation where Chichi practiced 66 more hours than Will.
