Answer: 9x-3x and 5x+x
Step-by-step explanation:
1. Brianna's thinking is incorrect because of course, when x is 0, the expression will equal whatever value isn't an x term. To find equivalent expression, you actually need to find which expressions have the same amount of x terms and the same value.
2. Expressions A and C are equivalent.
3. Expression A can be simplified, as you can do 9x - 3x = 6x, so your final expression would be 6x - 4. Expression C can also be simplified with 5x + x = 6x, which can then also be written as 6x - 4. This means both expressions have the same amount of x terms, and the same value, so they are equivalent.
Answer:
Below
Step-by-step explanation:
Brianna's teacher asks her which of these three expressions are equivalent to each other
Expression A: 9x−3x−4 Expression B: 12x−4 Expression C: 5x+x−4
Brianna says that all three expressions are equivalent because the value of each one is −4 when x=0.
Brianna's thinking is incorrect. Identify the error in Brianna's thinking. Determine which of the three expressions are equivalent. Explain or show your process in determining which expressions are equivalent. Enter your answers and your explanation or process in the space provided.
So let's just simplify A and C. B is already simplified.
9x-3x-4
6x-4
5x+x-4
6x-4
So yes, Brianna is incorrect. She added 3x and 9x, instead of subtracting 3x from 9x. A and C are equivalent, but B is all alone.

Answer:
x = -72
Step-by-step explanation:
Using algebra:
⇒ [tex]-\frac{x}{8} -11 = 2[/tex] (First add 11 to both sides of "=")
⇒ [tex]-\frac{x}{8} =9 (11 + -2)[/tex] (The multiply both sides by "8")
⇒ [tex]-x = 9*8[/tex] (Lastly the answer is 72 when x-value is negative, so when x-value will be positive the answer will be opposite of 72 which is -72)
⇒ [tex]x = -72[/tex]

Here is to my last q
Answers
Mean: average (add all values then divide by the amount of number)
Median: middle number
Mode: 80 (appears the most)
Mean: 95 + 80 + 80 + 85 + 80 + 85 + 90 = 595/7 = 85, the mean is 85
Median first put them in order
80, 80, 80, 85, 85, 90, 95
The median is the middle which is 85
Which statement matches?
Solution: D
Answer: D (Mean is 85)
Explanation:
"The list below shows the quiz scores for a group of students.
95, 80, 80, 85, 80, 85, 90"
The choices talk about median and mode so we find those first:
Median: find by taking which is the middle number when the data is from low to highest
1) rearrange them from low to high
80, 80, 80, 85, 85, 90, 95
2) find middle number
80, 80, 80, 85, 85, 90, 95
The median is 85
Mean: mean is the average of all numbers. Find by adding numbers and dividing by amount of numbers
1) add 80, 80, 80, 85, 85, 90, 95 and get 595
2) There are 7 total numbers so do 595/7 = 85
The mean is 85
D is the correct answer
why?
A is wrong because they are 85 not 80
B is wrong because it is 85 not 80
C is wrong because it is 85 not 80
D is right because it is 85!

Here is Laila’s graph from the previous screen.
Write your own equation in the form y=mx+b that could represent Laila’s graph.
Answers
Answer:
y=-1/3x+8
Step-by-step explanation:
There is no need for any specific answers, but here is one that could logically work out. Since the graph is going left/down, it has a negative slope, so -1/3 would be reasonable. The graph doesn't cross the origin and crosses above it, so this equation must have a positive 'b' value. In this case, I chose 8. y=-1/3+8 could represent Laila's graph.

120 blocks total
Step-by-step explanation:
All of the little cubes have side length 2" Thus, the 11" height of the box cannot be used entirely: we waste the top 1" because the five layers of little cubes reach only to 10" from the bottom.
Start at the bottom of the box. The dimensions of the bottom are 12" by 8". Along the longer side we can lay 6 blocks (which add up to 12" and are 2" wide. We can add 3 more such rows to fill the available 8" width of the box bottom. That's 6*4, or 24 blocks.
We can add 4 more 6 block by 4 block layers before we have the maximum 5 layers stacked in the box.
5 layers times 24 blocks per layer comes to 120 blocks total.
