x + 50 = 120
50x = 120
50 + 120 = x
x - 120 = 50

1 answer

Let's analyze each question one by one:

  1. Jalen is saving for a new tablet: Jalen needs to save a total of $120 and has already saved $50. The equation to represent how much more he needs to save (x) is: \[ x + 50 = 120 \] Correct answer: x + 50 = 120

  2. Isabella bought packs of stickers: Each pack costs $3, and she spent a total of $18 on stickers. The equation that represents the number of packs (x) she bought is: \[ 3x = 18 \] Correct answer: 3x = 18

  3. Byron's savings account: Byron spent $40 and has $80 left. Let x be the amount of money he had before spending. The equation to find how much he had is: \[ x - 40 = 80 \] Rearranging gives: \[ x = 80 + 40 = 120 \] Correct answer: x = $120

  4. Zayan brought Oreos: Zayan shares Oreos with 8 friends, giving each friend 3 Oreos. The equation representing the total number of Oreos (x) Zayan brings is: \[ 3x = 8 \] This seems to be a bit off since he should have given away a total of \(3 \times 8 = 24\) Oreos. The equation based on number of Oreos is: \[ x = 3 \times 8 = 24. \] But the closest answer available that matches \(3 \times x = 24\) is: \[ x/3 = 8; x = 24 \] Correct answer: x/3 = 8; x = 24

So, the correct answers are:

  1. \(x + 50 = 120\)
  2. \(3x = 18\)
  3. \(x = 120\)
  4. \(x/3 = 8; x = 24\)
