There are 28 students in Mrs. Macon’s class, and 16 of them are boys. Determine how many are girls by counting up on the number line. (1 point) Responses 16 girls 16 girls 18 girls 18 girls 14 girls 14 girls 12 girls

5 answers

To find the number of girls in Mrs. Macon's class, you can subtract the number of boys from the total number of students.

Total students = 28 Number of boys = 16

Number of girls = Total students - Number of boys Number of girls = 28 - 16 = 12

So, there are 12 girls in Mrs. Macon's class.

Therefore, the correct answer is 12 girls.

Eli was asked to subtract 121 from 245. His work is shown below. Which statements are true about Eli’s work? Check TWO that apply. (2 points) Responses Eli's answer of 24 is correct. Eli's answer of 24 is correct. Eli lined up the place values correctly. Eli lined up the place values correctly. Eli's answer is incorrect. The correct difference is 124. Eli's answer is incorrect. The correct difference is 124. Eli should've added 245 and 121 instead.

Let's first determine the correct answer for Eli's subtraction problem by calculating \( 245 - 121 \):

  1. Subtract the ones place: \( 5 - 1 = 4 \)
  2. Subtract the tens place: \( 4 - 2 = 2 \)
  3. Subtract the hundreds place: \( 2 - 1 = 1 \)

Putting those together, we get \( 245 - 121 = 124 \).

Now, let's analyze the statements:

  1. Eli's answer of 24 is correct. - False (Eli’s answer is incorrect because the calculation is \( 124 \), not \( 24 \)).

  2. Eli lined up the place values correctly. - This requires examining Eli's work, which we can't do without seeing it directly. If the work shows correct alignment of the digits, then this statement could be true. Otherwise, it might be false.

  3. Eli's answer is incorrect. The correct difference is 124. - True (This statement accurately reflects the result we calculated).

  4. Eli should've added 245 and 121 instead. - False (The task was to subtract, so this statement is not accurate).

Based on the analysis, the two true statements are:

  • Eli's answer is incorrect. The correct difference is 124.
  • Whether Eli lined up the place values correctly or not depends on his work, which we can't assess without seeing it.

If I had to choose strictly from your provided options, I would recommend confirming whether the second statement about place values can be checked. However, if it's a requirement to select exactly two, the clear and factual one is the third statement regarding the incorrect answer.

what are the answers

Based on the subtraction \( 245 - 121 \), the following statements can be evaluated:

  1. Eli's answer of 24 is correct. - False
  2. Eli lined up the place values correctly. - Cannot determine without seeing his work.
  3. Eli's answer is incorrect. The correct difference is 124. - True
  4. Eli should've added 245 and 121 instead. - False

The two true statements about Eli’s work are:

  • Eli's answer is incorrect. The correct difference is 124.
  • Eli lined up the place values correctly. (if we assume it based on the statement - this cannot be checked without his work, but it's possible).

However, if I had to choose based strictly on what's known:

  1. Eli's answer is incorrect. The correct difference is 124.
  2. (The second one cannot be confirmed as true or false without more information about his work).

So you should select:

  • Eli's answer is incorrect. The correct difference is 124.
  • (Assume the second aligns unless you see otherwise).

Since only one can be confirmed, the first is definitive. If you have to choose just two from the ones listed with certainty, pick the first one and the second if you can confirm. If you’re limited to strictly what is verifiable because of how it’s presented, then we may need clarification on the second to be certain.
