Bilangan yang benar untuk mengisi a, b, dan c adalah ....
Correct Answer
C. -2, -1, 1

Kalimat penjumlahan dari garis bilangan di atas adalah ....
Correct Answer
C. 7 + (-9 )= -2
Explanation
The correct answer is 7 + (-9) = -2. This is because when we add a positive number (7) and a negative number (-9), we subtract the absolute value of the smaller number from the absolute value of the larger number and give the result the sign of the larger number. In this case, the absolute value of 7 is larger than the absolute value of -9, so we subtract 9 from 7 and give the result the negative sign, resulting in -2.

a. -25
b. 25
c. -71
d. 71
Correct Answer
C. -71
Explanation
The correct answer is -71 because when subtracting a negative number from another negative number, the result is obtained by adding the absolute values of the numbers and keeping the negative sign. In this case, the absolute value of -48 is 48 and the absolute value of -23 is 23. Adding 48 and 23 gives us 71 and since both numbers are negative, the result is -71.

Hasil dari -56 - (-18) adalah ....
a. 74
b. -74
c. -38
d. 38
Correct Answer
C. -38
Explanation
The expression -56 - (-18) can be simplified by removing the double negative. When we subtract a negative number, it is equivalent to adding the positive version of that number. So, -56 - (-18) becomes -56 + 18, which equals -38.

42- (-25) = n. Nilai n adalah ....
a. -17
b. 17
c. 67
d. -67
Correct Answer
C. 67
Explanation
The correct answer is 67 because when subtracting a negative number from a positive number, the two negatives cancel each other out and the result is a positive number. In this case, 42 minus negative 25 is equivalent to 42 plus 25, which equals 67.

Hasil dari 65 + (-87) adalah ....
a. -22
b. 152
c. 22
d. -152
Correct Answer
A. -22
Explanation
The given question asks for the result of adding 65 and -87. When adding a positive number and a negative number, we subtract the smaller number from the larger number and give the result the sign of the larger number. In this case, 65 is larger than 87. So, we subtract 87 from 65 and give the result the negative sign. Therefore, the correct answer is -22.

(-10) : 2 + 15 - (-25) = ....
a. 30
b. -15
c. 35
d. -10
Correct Answer
C. 35
Explanation
The given expression involves addition and subtraction of integers. The expression can be simplified as follows: (-10) + 2 + 15 + 25. When we add these numbers, we get 32. However, since there is a negative sign in front of the 25, it means we are subtracting 25 instead of adding it. So, the expression becomes (-10) + 2 + 15 - 25, which equals -18. Therefore, the correct answer is not available.

Hasil dari 6 x (575 + 425) : 12 adalah ....
a. 300
b. 400
c. 500
d. 600
Correct Answer
C. 500
Explanation
The expression 6 x (575 + 425) : 12 can be simplified using the order of operations, which states that multiplication and division should be done before addition and subtraction. First, we calculate the sum inside the parentheses, which is 575 + 425 = 1000. Then, we multiply 6 by 1000, which gives us 6000. Finally, we divide 6000 by 12, resulting in 500. Therefore, the correct answer is 500.
