Question

Who is Correct. Please i need help it is for school.

Answer 1

neither of them

Explanation:

1. To prove that neither of them are correct, we have to work on the equation 2/5(b) + 1 = -11 ourselves.

2. (Solving)

Step 1: Subtract 1 from both sides. (This is where Tyler got it wrong)

• 
  `(2)/(5)b + 1 - 1 = -11 - 1`
• 
  `(2)/(5)b = -12` (this is where Mai got it wrong)

Step 2: Multiply both sides by 5/2.

• 
  `(2)/(5)b * (5)/(2) = -12 * (5)/(2)`
• 
  `b = (-60)/(2)`
• 
  `b = -30`

Step 3: Check if solution is correct.

• 
  `(2)/(5)(-30) + 1 = -11`
• 
  `(-60)/(5) +1 = -11`
• 
  `-12 + 1 = -11`
• 
  `-11 = -11`

3. As you can see, our solution is correct, but it doesn't match with either Mai or Tyler's works.

Therefore, the answer is neither of them are correct.
