Let's analyze each problem to determine which equation matches best.

  1. Darius is 38 years old. In 4 years he will be 3 times as old as Gia. How old is Gia?

    • In 4 years, Darius will be 38+4=42. Let Gia's age be g. According to the problem, 42=3g. Thus, Gia's age is g=14. The equation can be written as 3g=42, which simplifies to g=14.

  2. I think of a number, multiply it by 3 and then add four to get 42. What number am I thinking of?

    • Let the number be x. The equation is 3x+4=42 which simplifies to 3x=38.

  3. Lucia goes to the art store and spends $38. She buys a canvas for $20 and some new paints. If each paint costs $3, how many did she buy?

    • Let the number of paints be p. The equation is 20+3p=38, which simplifies to 3p=18 or p=6.

  4. Chelsea owes her mom $38. She starts paying her mom back $4 per week. After some weeks, she realizes she only owes her mom $2 more. How many weeks has she been paying her mom back?

    • Let the number of weeks be w. Chelsea's debt decreases as 4w. The equation can be set up as 38−4w=2, which simplifies to 4w=36.

  5. A rectangle has a length of 4 units and a width of x+3 units. If the area is 42, what is the value of x?

    • The area of a rectangle is given by the product of length and width: 4(x+3)=42.

Now, let's match the equations:

  • For problem 1: 3g=42 (not listed).
  • For problem 2: 3x+4=42 (matches option b: 3x+20=38 does not match).
  • For problem 3: 20+3p=38 (not listed).
  • For problem 4: 38−4w=2 (not listed).
  • For problem 5: 4(x+3)=42 (matches option e: 4(x+3)=42 but using '–=' seems to be an error).

The choices of equations presented:

  • a. 3x + 4 = 42 (correct for problem 2)
  • b. 3x + 20 = 38 (not applicable)
  • c. 4x + 2 = 38 (not applicable)
  • d. 3(x + 4) = 42 (not applicable)
  • e. 4(x + 3) = 42 (correct for problem 5, but seems to have a typo).

Based on the analysis, the correct matches are: 2 (3x + 4 = 42) from problem 2 and 5 (4(x + 3) = 42) from problem 5.

If we had to choose the best overall match, I would pick option a for problem 2 as most directly related.

can u pick for all of them?

Sure! Let's match each of the original problems with the provided equations:

  1. Problem: Darius is 38 years old. In 4 years he will be 3 times as old as Gia. How old is Gia?

    • Equation: This can be expressed as 38+4=3g or 42=3g. None of the provided options match this directly.
    • Best Match: None of the provided options.

  2. Problem: I think of a number, multiply it by 3 and then add four to get 42. What number am I thinking of?

    • Equation: 3x+4=42.
    • Best Match: a. 3x+4=42.

  3. Problem: Lucia goes to the art store and spends $38. She buys a canvas for $20 and some new paints. If each paint costs $3, how many did she buy?

    • Equation: The equation can be set up as 20+3p=38, which simplifies to 3p=18.
    • Best Match: None of the provided options.

  4. Problem: Chelsea owes her mom $38. She starts paying her mom back $4 per week. After some weeks she realizes she only owes her mom $2 more. How many weeks has she been paying her mom back?

    • Equation: This can be expressed as 38−4w=2 or 4w=36.
    • Best Match: None of the provided options.

  5. Problem: A rectangle has a length of 4 units and a width of x+3 units. If the area is 42, what is the value of x?

    • Equation: The area is given by 4(x+3)=42.
    • Best Match: e. 4(x+3)=42.

Summary of Matches:

  1. Darius & Gia: None
  2. Number problem: a. 3x+4=42
  3. Lucia's paints: None
  4. Chelsea's repayment: None
  5. Rectangle area: e. 4(x+3)=42
