QuestionIdentify the incorrect answer among the three math quiz questions and explain why.
1. $-11+(-7)=-4$
2. $29+(-18)=11$
3. $-16+35=19$

Studdy Solution

STEP 1

Assumptions1. The solutions provided for each question are as follows - QUESTION\#1 -11 + (-7) = -4 - QUESTION\#29 + (-18) =11 - QUESTION\#3 -16 +35 =19

STEP 2

We will verify the correctness of each solution by performing the operations given in the questions.

STEP 3

Let's start with QUESTION\#1. We need to add -11 and -7.
$-11 + (-7)$

STEP 4

Perform the addition operation.
$-11 + (-7) = -18$

STEP 5

Compare the calculated result with the provided solution for QUESTION\#1. The provided solution is -4, but our calculated result is -18. Therefore, the solution for QUESTION\#1 is incorrect.

STEP 6

Now, let's verify QUESTION\#2. We need to add29 and -18.
$29 + (-18)$

STEP 7

Perform the addition operation.
$29 + (-18) =11$

STEP 8

Compare the calculated result with the provided solution for QUESTION\#2. Both the provided solution and our calculated result are11. Therefore, the solution for QUESTION\#2 is correct.

STEP 9

Finally, let's verify QUESTION\#3. We need to add -16 and35.
$-16 +35$

STEP 10

Perform the addition operation.
$-16 +35 =19$

STEP 11

Compare the calculated result with the provided solution for QUESTION\#3. Both the provided solution and our calculated result are19. Therefore, the solution for QUESTION\#3 is correct.
The incorrect solution is QUESTION\#. The correct solution should be -18, not -4.

STEP 2

We will verify the correctness of each solution by performing the operations given in the questions.

STEP 3

Let's start with QUESTION\#1. We need to add -11 and -7.−11+(−7)-11 + (-7)−11+(−7)

STEP 4

Perform the addition operation.−11+(−7)=−18-11 + (-7) = -18−11+(−7)=−18

STEP 5

Compare the calculated result with the provided solution for QUESTION\#1. The provided solution is -4, but our calculated result is -18. Therefore, the solution for QUESTION\#1 is incorrect.

STEP 6

Now, let's verify QUESTION\#2. We need to add29 and -18.29+(−18)29 + (-18)29+(−18)

STEP 7

Perform the addition operation.29+(−18)=1129 + (-18) =1129+(−18)=11

STEP 8

Compare the calculated result with the provided solution for QUESTION\#2. Both the provided solution and our calculated result are11. Therefore, the solution for QUESTION\#2 is correct.

STEP 9

Finally, let's verify QUESTION\#3. We need to add -16 and35.−16+35-16 +35−16+35

STEP 10

Perform the addition operation.−16+35=19-16 +35 =19−16+35=19

STEP 11
