7 C

+7 C

-7 C

+ 7 C

The correct answer is -7 C. This is because the question asks for the correct writing of "7 C" below zero. The minus sign before the 7 indicates that the temperature is below zero, making it negative. Therefore, the correct way to write "7 C" below zero is "-7 C".

Explanation

The correct answer is -7 C. This is because the question asks for the correct writing of "7 C" below zero. The minus sign before the 7 indicates that the temperature is below zero, making it negative. Therefore, the correct way to write "7 C" below zero is "-7 C".

2. Suhu pada suatu ruangan 28 C, karena suatu sebab ruangan mengalami penurunan suhu secara drastis yaitu 35 C, maka suhu ruangan tersebut menjadi ....

-4 C

5 C

-6 C

-7 C

The initial temperature of the room is 28°C. Due to a drastic decrease in temperature of 35°C, the room's temperature will be lowered by 35°C. Therefore, the final temperature of the room will be 28°C - 35°C = -7°C.

Explanation

The initial temperature of the room is 28°C. Due to a drastic decrease in temperature of 35°C, the room's temperature will be lowered by 35°C. Therefore, the final temperature of the room will be 28°C - 35°C = -7°C.

3. Nilai dari 100 : (-5) = ... .

20

5

-5

-20

The correct answer is -20 because when you subtract -5 from 100, you are essentially adding 5 to 100. So, 100 + 5 equals 105. However, since we are subtracting -5, the answer becomes 105 - 5, which equals 100. Therefore, the correct answer is -20.

Explanation

The correct answer is -20 because when you subtract -5 from 100, you are essentially adding 5 to 100. So, 100 + 5 equals 105. However, since we are subtracting -5, the answer becomes 105 - 5, which equals 100. Therefore, the correct answer is -20.

4. Nilai 5 + (-9) = ... .

-14

-4

4

14

The given expression is a sum of two numbers, 5 and -9. When we add a positive number and a negative number, we subtract the absolute value of the smaller number from the absolute value of the larger number and keep the sign of the larger number. In this case, the absolute value of 5 is larger than the absolute value of -9. Therefore, we subtract 9 from 5 and keep the sign of 5, which is positive. So, the result is -4.

Explanation

The given expression is a sum of two numbers, 5 and -9. When we add a positive number and a negative number, we subtract the absolute value of the smaller number from the absolute value of the larger number and keep the sign of the larger number.

5. Pernyataan yang benar adalah ....

> 5

-1 > -3

0 < -2

-6 > -1

The correct answer is -1 > -3 because when comparing two numbers, the greater number is placed on the left side of the inequality symbol. In this case, -1 is greater than -3, so the statement -1 > -3 is true.

Explanation

The correct answer is -1 > -3 because when comparing two numbers, the greater number is placed on the left side of the inequality symbol. In this case, -1 is greater than -3, so the statement -1 > -3 is true.
