Plz help this due soon!
I know that. That’s why I’m doing my work I didn’t ask for all the answers I just wanted help. I’ve been doing my work sense I posted this so I know and I’m not relying on stranger to give me all of the answer but I would gladly help anyone that ask because I’m done with the work.
Kira, you will now show us the answers
Sure, I can help you with these math questions. Let's go through each question step by step.
1. Simplify the expression: –12 ÷ 3 • (–8 + (–4)2 – 6) + 2
To simplify this expression, we will follow the order of operations (PEMDAS/BODMAS).
First, we simplify the expression inside the parentheses:
–8 + (–4)2 – 6 = –8 + 16 – 6 = 2
Next, we perform the multiplication and division from left to right:
–12 ÷ 3 • 2 + 2 = –4 • 2 + 2 = –8 + 2 = –6
So, the simplified expression is –6.
2. Solve the equation: –30 + k = 9
To solve this equation, we want to isolate the variable k on one side of the equation.
First, we can simplify the equation:
–30 + k = 9
Then, we can isolate k by subtracting –30 from both sides:
k = 9 + 30
k = 39
So, the solution is k = 39. Answer choice D.
3. Find the additive inverse of 22.
The additive inverse of a number is the number that, when added to the original number, gives a sum of zero.
So, to find the additive inverse of 22, we need to find the number that when added to 22 gives us zero.
–22 is the additive inverse of 22, because 22 + (–22) = 0.
So, the additive inverse of 22 is –22. Answer choice B.
4. Solve the equation: z + 9 = –18
To solve this equation, we want to isolate the variable z on one side of the equation.
First, we can simplify the equation:
z + 9 = –18
Then, we can isolate z by subtracting 9 from both sides:
z = –18 – 9
z = –27
So, the solution is z = –27. Answer choice A.
5. Evaluate the expression: (10 – 6)2 + 6 • 2 – (3 + 2)2
To evaluate this expression, we follow the order of operations (PEMDAS/BODMAS).
First, we simplify the arithmetic inside the parentheses:
(10 – 6)2 + 6 • 2 – (3 + 2)2 = 4^2 + 6 • 2 – 5^2 = 16 + 12 – 25 = 3
So, the value of the expression is 3. Answer choice B.
6. Solve the equation: 8 • g = –32
To solve this equation, we want to isolate the variable g on one side of the equation.
First, we can simplify the equation:
8 • g = –32
Then, we can isolate g by dividing both sides by 8:
g = –32 ÷ 8
g = –4
So, the solution is g = –4. Answer choice B.
I hope this helps! Let me know if you have any further questions.
We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
