please help meh
Sure, I'd be happy to help you with these questions! Let's go through each one step by step:
1. Which of the following could be represented by –8?
To determine which option could be represented by –8, we need to understand what –8 represents. In this case, –8 represents a negative number. Let's analyze each option:
A. A drop of 8 meters: This represents a positive distance, so it is not –8.
B. 8 T-shirts: This represents a positive quantity, so it is not –8.
C. Sea level in 8 places of the world: This represents a neutral position, not –8.
D. 8°C above zero: This represents a positive temperature, so it is not –8.
Therefore, none of the options represents –8. The correct answer would be None of the above.
2. Compare. Use <, =, or >
To solve this comparison, we need to perform the operations and determine if the two expressions are equal, less than (<), or greater than (>):
Left side: 5 + (–4) = 1
Right side: –14 + (–7) = –21
1 is not equal to –21, so the correct answer is C. >
3. Order the integers from least to greatest.
To order the integers from least to greatest, we arrange them in ascending order:
–8, –5, 6, 11, 16
The correct answer is B. –8, –5, 6, 11, 16.
4. Find the sum.
To find the sum, we need to add the two numbers:
–8 + (–2) = –10
The correct answer is A. –10.
5. Find the difference.
To find the difference, we need to subtract the second number from the first:
–8 – (–7) = –1
The correct answer is D. –1.
6. Solve the equation.
To solve the equation, we need to isolate the variable (m) on one side of the equation:
m + 45 = 32
Subtract 45 from both sides:
m = 32 – 45
m = –13
The correct answer is B. –13.
7. Solve the equation.
To solve the equation, we need to isolate the variable (v) on one side of the equation:
–13v = 195
Divide both sides by –13:
v = 195 / –13
v = –15
The correct answer is D. –15.
I hope this explanation helps! If you have any further questions, feel free to ask.
