    • -12

    • -6

    • 0

    Correct Answer
    A. -6
    Explanation
    The correct answer is -6 because when you subtract 9 from 3, you are essentially moving 9 units to the left on the number line. Starting at 3 and moving 9 units to the left will bring you to -6.

    • -7

    • -49

    • 7

    • 49

    • Salah semua

    Correct Answer
    A. -49
    Explanation
    The given expression is -21 + (-28). When adding two negative numbers, we add their absolute values and keep the negative sign. Therefore, the absolute values of -21 and -28 are 21 and 28 respectively. Adding them gives us 49. Since both numbers are negative, the result is -49.

    • -24

    • 4

    • 5

    Correct Answer
    A. -6
    Explanation
    The given expression involves adding three numbers: -15, 13, and -4. When we add -15 and 13, we get -2. Then, when we add -2 and -4, we get -6. Therefore, the correct answer is -6.

    Rate this question:

    • -31

    • 31

    • Salah semua

    Correct Answer
    A. 31
    Explanation
    The correct answer is 31 because when you subtract a negative number from a positive number, you add the two numbers together. In this case, 18 minus (-13) is the same as 18 plus 13, which equals 31.

    Rate this question:

  • 6. 

    -35   -  18

    • 17

    • -17

    • -53

    • -63

    Correct Answer
    A. -53
    Explanation
    The correct answer is -53. To arrive at this answer, we subtract 18 from -35, which gives us -53.

    • -29

    • 3

    • -21

    • -5

    • 5

    Correct Answer
    A. -21
    Explanation
    The correct answer is -21. This is because when subtracting a negative number from another negative number, it is equivalent to adding the positive value of that number. Therefore, -12 - 13 + 4 equals -21.

    Rate this question:

  • 8. 

    -45   -  (-28)

    • 17

    • -73

    • -17

    • 73

    • 72

    Correct Answer
    A. -17
    Explanation
    The correct answer is -17. This can be determined by subtracting -28 from -45, which gives us -17.

    Rate this question:

  • 9. 

    Suhu di puncak gunung -6o C, karena terjadi hujan salju,suhunya turun lagi 8o C, berapakah suhu udara di puncak gunung tersebut setelah turun hujan ?

    • 2 derajat celcius

    • -2 derajat celcius

    • 14 derajat celcius

    • -14 derajat celcius

    • -6 derajat celcius

    Correct Answer
    A. -14 derajat celcius
    Explanation
    After the snowfall, the temperature on the mountain peak decreases by 8 degrees Celsius. Since the initial temperature was -6 degrees Celsius, subtracting 8 degrees Celsius from it gives us -14 degrees Celsius. Therefore, the air temperature on the mountain peak after the rain is -14 degrees Celsius.

    Rate this question:

  • 10. 

    .Suhu udara di dalam lemari es             -10o C,setelah listrik mati sebentar suhu menjadi 1o C,Berapa derajat perubahan suhu terjadi ?

    • 9 derajat

    • -9 derajat

    • 11 derajat

    • -11 derajat

    • 0 derajat

    Correct Answer
    A. 11 derajat
    Explanation
    The temperature inside the refrigerator was initially at -10o C. After a short power outage, the temperature increased to 1o C. Therefore, the temperature change is calculated by subtracting the initial temperature from the final temperature, which is 1o C - (-10o C) = 11o C. Hence, the correct answer is 11 derajat.
