zach says that the expressions 6x - 36 and 3(2x -12) are equivalent
Answer:
True
Step-by-step explanation:
When you distribute the 3, you get x(2x3)-(12x3)
2x3=6
12x3=36
so 6x-36
and that is equivalent to the first expression.
0.2x+2.7x-8.1=6.9+1.1x

The sum of 2x50 and 3x50 is ____ x 50?
5
Simply add 3 and 2. You dont need to worry about the 50.
Or, complete 2x50 and 3x50
Now you would have 100 and 150.
Then add them to get 250.
Finally, divide 250 by 50.
Your answer should be 5

i will give brainliest and 15pts
Answer: what you need to do is multiply 3 times 1 and add 2 to the sum that you get which would be 5/3 for the first one because you keep the same denominator! Just multiply the denominator the bottom number and add the numerator the top number to your sum that you got from multiplication! Do that for all of them and you should get an improver fraction!

Finding the reciprocal is easy just flip the numbers I’m in 6th grade I learn this already!
For example just flip 3/7 to 7/3
Answer:
1. 5/2 2. 18/5 3. 35/5 4. 38/3 5. 72/7 1. 7/3 2. 3/8 3. 1/9 4. 8/33 5. 3/44
Step-by-step explanation:
to make mixed numbers into improper fractions, you multiply the whole number by the denominator, and add the numerator. you take that answer and make it the numerator in the new improper fraction, and keep the same denominator.
to take the reciprocal switch the numerator and the denominator.

Is m || n? Which theorem (which tool) did you use to decide?
Answer:
Yes. m is parallel to n. Since the 2 angles labelled are equal, by alternate angles rule, m is parallel to n.

For the terms and like terms just put:
T:
LT:
Answer:
T: x^2 & 3 LT: -x & -3x
Step-by-step explanation:
x^2 has no other like term like: -x^2, 8x^2 or basically no longer "x^2"
3 is the same ^ there is no other single integer
(We cannot use -3x because it has an x attached to it)
-x & -3x are like terms because they both have an x to it a single x, not a x with an exponent like x^2
so -x + (-3x) would equal -4x if we wanted to solve it
Answer:
Terms: 3, (-x), x², (-3x)
Like terms: (-x) and (-3x)
Step-by-step explanation:
A term is a single number (positive or negative), a single variable (a letter), or several variables multiplied but not added or subtracted.
Like terms are terms that have the same variables and power like -x.
Select all that apply.
Which of the following are proportions?
25/10 = 5/2
3/4 = 8/10
2/8 = 3/12
3/4 = 15/20
Answer:
Step-by-step explanation:
3/4=15/20 are proportions
For every 3 you get a 4
So 5*3= 15 and 5*4=20
25/10 = 5//2 is another one.
Answer:
25/10 = 5/2
3/4 =15/20

The value 1 is a solution for x^2-6x+5=0
A. True
B. False
Answer:
The complex solution would be: X = 5,1
Step-by-step explanation:
Answer:
x=1
TRUE because Factoring x2-6x+5
The first term is, x2 its coefficient is 1 .
The middle term is, -6x its coefficient is -6 .
The last term, "the constant", is +5
Step-1 : Multiply the coefficient of the first term by the constant 1 • 5 = 5
Step-2 : Find two factors of 5 whose sum equals the coefficient of the middle term, which is -6 .
-5 + -1 = -6 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -5 and -1
x2 - 5x - 1x - 5
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-5)
Add up the last 2 terms, pulling out common factors :
1 • (x-5)
Step-5 : Add up the four terms of step 4 :
(x-1) • (x-5)
Which is the desired factorization
Suppose a least squares regression line is given by y= 4.302x - 3.293. What is the mean value of the response variable if x = 20?
Answer:
i think this is the answer
Step-by-step explanation:
[tex]4.302(20) - 3.293 = 82.747[/tex]
The mean value of the response variable is 82.747.
What is Regression line?Linear Regression calculates the equation of the line that is the best fit for the given data points. Linear regression models a linear relationship between the input variable x and the output variable y.
Here, given regression line;
y= 4.302x - 3.293 ...............(i)
Now, value of x is given; x = 20
Put the value of x in equation (i), we get
y = 4.302 X 20 - 3.293
y = 86.04 - 3.293
y = 82.747
Thus, the mean value of the response variable is 82.747.

Complete the following steps to receive full credit for this question:
• The inequality translated in numerical form
• Your work solving the inequality
• The solution graphed on a number line
• The solution in set notation
• The solution in interval notation
Answer:
The required inequality is: 12 ≤ 3x < 21
Step-by-step explanation:
We are given: three times a number is greater than or equal to 12 and less than 21
We need to answer following questions:
1) The inequality translated in numerical form
Let number = x
12 ≤ 3x < 21
2) Your work solving the inequality
We need to find value of x. Divide the inequality by x
4 ≤ x < 7
3) The solution graphed on a number line
It is shown in figure attached.
4) The solution in set notation
The set notation is: Considering x belongs to natural numbers N
{∀ x|x∈N, 4 ≤ x < 7}
5) The solution in interval notation
The interval notation is: [4,7)
because we have 4 less than equal to x and x is less than 7

Step-by-step explanation:
1. A newspaper headline claims: "Apple spends far less on Research & Development
than any of its rivals." Further into the story, the reporter writes that Apple spends a
paltry 2% of revenues compared with 14% at Google and Microsoft.
a. What is the mistaken assumption here?
b. Why is that assumption incorrect?
c. Is there a situation where the headline is still correct?
Answer:
Step-by-step explanation:
a)
The mistaken assumption is that Apple spends "far less" on Research and Development than any of its rivals.
b)
The assumption is incorrect because it took cognizance of the percentage used, and not the actual money spent. In truth, Apple generates far more income than the other two rivals. With Apple generating over $100bn in the said time span, and Google generating $37bn. At the end of the day, Apple spends $2.1bn on Research and Development, while Google spends $5.3bn on the same. This is quite close than the quoted distance of 14% - 2%
c)
Yes, I think so. But only when the 3 companies generate almost the same revenue.
Based on the description of the headline given in the scenario, the solution to the problems posed are :
A.)
The mistake in the assumption is that, the headline focused just on the percentage of the revenue made by each company that is spent on R&D.
B.)
The assumption is incorrect because, the revenue generated by the companies aren't the same. Hence, making comparison based on the percentage alone is incorrect.
C.)
The headline may be correct only when the revenue generated by each company is the same.

The total cost in dollars for Larry to have his birthday party at a local
Trampoline Park can be found using the function t = 6.95p + 29.95, where p is
the number of people who will attend the party. If Larry only has $70 to spend on
his party, which of the following could represent the domain of the function?
Answer:
[tex]0 \leq p < 6[/tex]
Step-by-step explanation:
Given
[tex]t = 6.95p + 29.95[/tex]
[tex]Amount = 70[/tex]
Required
Determine the domain
First, we need to solve for p
Substitute 70 for t in [tex]t = 6.95p + 29.95[/tex]
[tex]70 = 6.95p + 29.95[/tex]
Collect Like Terms
[tex]6.95p = 70 - 29.95[/tex]
[tex]6.95p = 40.05[/tex]
Solve for p
[tex]p = 40.05/6.95[/tex]
[tex]p = 5.76[/tex]
This implies that Larry can not invite up to 6 people.
Hence, the domain can be represented as: [tex]0 \leq p < 6[/tex]
