Step-by-step explanation:
I feel something is off about this question
But going with What you typed
It said
The Number at tens position is twice that at unit
therefore
If the unit number is x
The Tens Number will be= 2x
Now
Grab this concept
If we want to write a 2digit number 49
we can say 10x4 + 9 which is the same as 49.
So
The original number is 10x2x + x
Now
27 is subtracted from this number and the digits are reversed
When the digits are reversed; The Tens position will now be x and Unit will be 2x... This new 2digit number will be 10xX + 2x
So applying what we know
27 - (Original number) = Reversed
27 - (10x2x + x) = 10xX + 2x
27 = 10xX + 2x + (10x2x + x)
27 = 10x +2x + 20x + x
27 = 33x
x = 27/33
x=9/11
The original Number is 10x2x + x
= 10x2(9/11) + 9/11
=10x18/11 + 9/11
180/11 + 9/11
=189/11.

find the difference. express the answer in scientific notations
(8.64×10²⁰)-(7.83×10²⁰)
=======================================================
Explanation:
Ignore the 10²⁰ portions. We can replace them with the variable m, or whatever letter you like
So the original expression becomes 8.64m - 7.83m which simplifies to 0.81m
Basically you subtract the values without the m, so 8.64-7.83 = 0.81
Then you tack on the m at the end.
The 0.81 itself is not in scientific notation, but we can fix that like so:
0.81 = 8.1*10^(-1)
Furthermore, we can say:
0.81m = 8.1*10^(-1)*m
0.81m = 8.1*10^(-1)*10^(20)
0.81m = 8.1*10^(-1+20)
0.81m = 8.1*10^(19)

You’re purchasing a new television with a 32” screen. The 32” measurement represents the diagonal measurement of the screen. You remember the height at the store was 16”. What is the width of the TV
Answer:
27.7"
Step-by-step explanation:
use the pythagorean theorem
a² + b² = c²
a² + 16² = 32²
a² + 256 = 1,024
subtract 256 from both sides
a² = 768
Take the square root of both sides
a = 27.7128129211
a = 27.7"

Enter the explicit rule for the geometric sequence.
1/4, 1/2, 1, 2, 4, …
Answer:
[tex]a_n = (\frac{1}{4})2^{n-1}[/tex]
Step-by-step explanation:
Geometric sequence:
In a geometric sequence, the quotient between consecutive terms is the same, and this quotient is given by q.
The explicit rule of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
1/4, 1/2, 1, 2, 4
This means that [tex]a_1 = \frac{1}{4}[/tex], and:
[tex]q = \frac{4}{2} = \frac{2}{1} = \frac{1}{\frac{1}{2}} = \frac{\frac{1}{2}}{\frac{1}{4}} = 2[/tex]
So the explicit rule is:
[tex]a_n = (\frac{1}{4})2^{n-1}[/tex]

A ratio expresses the number of times one number contains another. The ratio of the given polynomial is equal to 3.
What is a Ratio?A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given the polynomial function, f(x)=(6x³ - x)/(2x³ - x). The leading coefficient is the constant of the term that has the highest power in a given polynomial. Therefore, the leading coefficient of the numerator and the denominator are 6 and 2, respectively. Thus, the ratio of the constant is,
Ratio = 6/2 = 3
Hence, the ratio of the given polynomial is equal to 3.

4. Two friends, Sequoia and Raven, sold organic chap sticks at the local market.
Sequoia sold her chap sticks for $4 and Raven sold hers for $3 each. In the first hour, their total combined
sales were $20.
If Sequoia sold. chap sticks and Raven sold y chap sticks, then the following equation can be formed:
4x + 3y = 20
In the first hour, the friends sold a total of 6 chap sticks between them.
Find the number of chap sticks each of the friends sold during this time by forming a second equation and
solving the simultaneous equations graphically.
Answer:
Sequoia sold 2 chap sticks while Raven sold 4.
Step-by-step explanation:
Since two friends, Sequoia and Raven, sold organic chap sticks at the local market, and Sequoia sold her chap sticks for $ 4 and Raven sold hers for $ 3 each, and in the first hour, their total combined sales were $ 20, if in the first hour, the friends sold a total of 6 chap sticks between them, to determine the number of chap sticks each of the friends sold during this time the following calculation must be performed:
6 x 4 + 0 x 3 = 24
5 x 4 + 1 x 3 = 23
2 x 4 + 4 x 3 = 20
Therefore, Sequoia sold 2 chap sticks while Raven sold 4.

What is the solution to the equation 5x-7= 3x+5?
Ox=1
O x = 6
O x = 12
O x = 24
x = 6
Step-by-step explanation:
Step 1: Group all y terms on the left side of the equation
Subtract 3x from both sides:
5x - 7 = 3x + 5
5x - 7 -3x = 3x + 5 - 3x
2x - 7 = 3x + 5 - 3x
2x - 7 = 5
Step 2: Group all constants on the right side of the equation
Add 7 to both sides of the equation:
2x - 7 = 5
2x - 7 + 7 = 5 + 7
2x = 5 + 7
2x = 7
Step 3: Isolate the y
Divide both sides of the equation by 2:
2x = 12
2x/2 = 12/6
x = 12/2
x = 6
The solution of the given expression is x = 6.
What is an expression?In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.
Subtract 3x from both sides:
5x - 7 = 3x + 5
5x - 7 -3x = 3x + 5 - 3x
2x - 7 = 3x + 5 - 3x
2x - 7 = 5
Add 7 to both sides of the equation:
2x - 7 = 5
2x - 7 + 7 = 5 + 7
2x = 5 + 7
2x = 7
Divide both sides of the equation by 2:

PLEASE HE L P IT WOULD mean the world to me<3..............................................................................................................................................................................Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
The weekly paycheck amount for each salesman, p, is a function of the number of sales, s, they had in that week.
Is the function representing the weekly paycheck amount of Salesman A a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman B a proportional relationship? Use complete sentences to explain your reasoning.
Is the function representing the weekly paycheck amount of Salesman C a proportional relationship? Use complete sentences to explain your reasoning.
Answer:
Let x represent the number of sales each man had.
For Salesman A, he earns $65 per sale; this is 65x.
For Salesman B, he earns $40 per sale; this is 40x. We also add to this his weekly salary of $300; this gives us 40x+300.
Since their pay was equal, set the two expressions equal
Step-by-step explanation:
65x = 40x+300
Subtract 40x from each side:
65x-40x = 40x+300-40x
25x = 300
Divide both sides by 25:
25x/25 = 300/25
