-1/7(14+28p)-13=4(1/2p-3)-6p

Answer:

29 degrees Celsius are 84.2 Fahrenheit.

Step-by-step explanation:

In order to convert Celsius to Fahrenheit you can use this formula: [tex]F = C * 1.8 + 32[/tex].

Here we have [tex]F = 29 * 1.8 + 32[/tex] which equals 84.2. Instead of 1.8 you can use the fraction [tex]\frac{9}{5}[/tex] if you wish so.

Answer:

[tex]\large\boxed{29^oC=84.2^oF}[/tex]

Step-by-step explanation:

Formula for converting Celsius (C) to Fahrenheit (F):

[tex]F=32+\dfrac{9}{5}C[/tex]

We have C = 29. Substitute:

[tex]F=32+\dfrac{9}{5}(29)=32+\dfrac{261}{5}=32+52.2=84.2[/tex]

Answer: Common

Step-by-step explanation:

The answer is with a multiplication of denominators, because when you multiply the denominator of one fraction with the denominator of the other fraction, we will get product which could divide between both denominator

for example if you have the following equation:

2/3+2/4

and you multiply 3*4 =12

and you can use it to complete the equation as a common denominator

10x = 4(2x -9)

10x = 8x - 36

10x - 8x = -36 - 8x

2x = -36

2x ÷ 2 = -36 ÷ 2

x = -18

Answer:

Step-by-step explanation:

f(n) = 3n + 2, n ≥ 1

Substitute n = 3:

f(3) = 3(3) + 2 = 9 + 2 = 11

The third term of the sequence is 11 given that that the sequence has a domain of n ≥ 1 and f(n) = 3n + 2. This can be obtained by substituting 3 in the sequence since we have to find the third term.

Given that, the sequence ⇒ f(n) = 3n + 2

Since n ≥ 1, first term will be ⇒ f(1) = 3(1) + 2 = 5

Second term will be f(2) = 3(2) + 2 = 8

Third term will be f(3) = 3(3) + 2 = 11

Thus the sequence is 5, 8, 11, ... and the third term is 11.

Hence the third term of the sequence is 11 given that that the sequence has a domain of n ≥ 1 and f(n) = 3n + 2.

Answer:

-20/35    if you simplify it would be -4/7

Step-by-step explanation:

Answer:  The answer is:  " 45  % "  .    

________________________________________________

               →    " Twenty-seven is 45 % of 60. "

________________________________________________

Step-by-step explanation:

________________________________________________

The question asks:

 " 27 is what % {percentage] of 60 " ?  ;

________________________

So:  " 27 =  (n/100) * 60 " ;  Solve for "n" ;

________________________________________________

Method 1:

________________________________________________

  →   (n/100) * 60 = 27 ;

Divide each side by 60 :

 →   [ (n/100)  * 60 ] / 60 = 27 /60 ;

to get:

 →    (n/100) = 27/60 ;

Now:  Cross-factor multiply:

 →  60n = (27)*(100) ;

to get:

 → 60n = 2700 ;

Divide each side by "60" ;

→  60n = 2700/ 60 ;

to get:  n = 45 ;

________________________

 →  The answer is:  45 % .    

   →  " Twenty-seven is 45 % of 60."

________________________________________________

Method 2:

________________________________________________

The question asks:

 " 27 is what % {percentage] of 60 " ?

________________________

To solve this problem:

Rephrase this question as:

________________________

" 27 is 60% of what number ? "

 →  The answer will be the same!

________________________

→  27 = (60/100)* n ;   Solve for "n" ;

Multiply each side of the equation by "100" ; to eliminate the fraction:

→  100 * 27 = 100 * [ (60/100)* n ] ;

 to get:

   →   2700 = 60n ;

↔  60n = 2700 ;

Divide Each Side of the equation by "60" ;

    →   60n/60 = 2700 / 60 ;

to get:  n = 45 ;

________________________________________________

→  The answer is:  45 % .    

       →  " Twenty-seven is 45 % of 60."

________________________________________________

Method 2:  Variant 1 of 2:

________________________________________________

When we have:

→  27 = (60/100)* n ;   Solve for "n" ;

________________________

Note that:  "(60/100) = (60÷ 100) = (6 ÷ 10)" ;   since:  in "(60/100)" ;  the "zero" from the "numerator" cancels out;  And:  the "last zero" in "100" — from the "denominator" cancels out;  since we are dividing "each side" of the fraction by "10" ;

  →   "(60÷10) / (600÷10)"  =  " 6/10 " ;  

  →   " (6/10)" ; that is;  "six-tenths"} ;  

  →     can be represented by:  " 0.6 " ;

  →  {by convention;  but specifically, here is the explanation} — as follows:

________________________

  →   "(6/10)" =  " (6 ÷ 10) " ;  

Note:  When dividing a number by "10" ;  we take the original number; and move the decimal point to the left; & then we rewrite that number as the "answer".  

Note:  When multiplying or dividing by a positive, non-zero integer factor of "10" that has at least 1 (one) "zero" after that particular factor of "10".  We can get the answer by taking the original number & moving the decimal point the number of spaces as designated by the number of zeros following the particular [aforementioned factor of "10".].

We move the decimal point to the right if we are multiplying;  and to the left  if we are dividing.  In this case, we are dividing "6" by "10 " :

 →  " 6   ÷  10  =  ? " ;  

 →  " 6.  ÷ 10 =  ? " ;

   We take the: " 6. " ;  and move the decimal point "one space backward [i.e. "to the left"];  since we are dividing by "10" ;

 →  to get:  " .6 " ;  & we rewrite this value as "0.6" in a rewritten equation:

________________________

So; we take our equation:

→  27 = (60/100)*n ;  And rewrite—substituting "0.6" for

"(60/100)"— as follows:

________________________

→  27 = (0.6)n ;  ↔ (0.6) n = 27 ;

Multiply each side of the equation by "10" ; to eliminate the decimal:

   →  10 * [ (0.6)n ]  = 27 * 10 ;

to get:

  →  6n = 270 ;

Divide each side of the equation by "6" ; to isolate "n" on one side of the equation; & to solve for "n" ;

 →  6n / 6  =  270 / 6 ;

to get:   n = 45 ;

________________________________________________

→  The answer is:  45 % .    

      →  " Twenty-seven is 45 % of 60."

________________________________________________

Method 2 (variant 2 of 2):

________________________________________________

We have the equation:  27 = (60/100)* n ;   Solve for "n" ;

________________________

Note:  From Method 2 (variant) 1 of 2— see above):

________________________

Note:  Refer to the point at which we have:

________________________

→   " {  (60÷10) / (600÷10)"  =  " (6/10) " ;  that is;  "six-tenths"} ;

________________________

Note that the fraction— "(6/10)" ;  can be further simplified:

→  "(6/10)" =  "(6÷2) / (10÷2)" = "(3/5)" ;

Now, we can rewrite the equation;

→ We replace "(60/100)" ;  with:  "(3/5)" :

    →  27 = (3/5)* n ;   Solve for "n" ;

↔ (3/5)* n = 27 ;  

↔    (3n/5) = 27 ;

Multiply Each Side of the equation by "5" ;

→  5* (3n/5) = 27 * 5 ;  

to get:

→   3n = 135 ;

Divide Each side of the equation by "3" ;  to isolate "n" on one side of the equation;  & to solve for "n" ;

→  3n / 3 = 135 / 3  ;

to get:   n = 45 ;

Answer: (-4,9)

Step-by-step explanation:

After applying the sequence of transformations, the coordinates of the final point are (-4, 9).

In Mathematics and Geometry, a reflection over or across the y-axis would maintain the same y-coordinate while the sign of the x-coordinate changes from positive to negative or negative to positive.

By applying a reflection over the y-axis to the coordinates of the point (4, -9), we have the following new coordinates for the image;

(x, y)                →      (-x, y)

(4, -9)           →     (-4, -9)

By applying a reflection over the x-axis to the coordinates of the point (-4, -9), we have the following new coordinates for the image;

(x, y)                →      (x, -y)

Answer:

x-axis scale, 0–30; label, Months

Y-axis scale, 0–9,000; label, Total Remaining Debt ($)

Step-by-step explanation:

According to given data

Debt = $8950

Monthly payment = $360

Now we can calculate the total period required to eliminate the debt

Total months to eliminate debt = Total Debt/Monthly installment

Total months to eliminate debt = 8950/360

Total months to eliminate debt = 24.8 months

Now, by this calculate, we can say that it is only logical to plot time in graph with months, not years or days. Because if we plot graph with days, it will be too lengthy, on the other hand, if we plot graph with years, it will shrink to much and it will become very difficult to read it and estimate the progress. So all options with time in other than month will be eliminated and we will be left with option B. Notice that option a will be eliminated because we need to plot graph for 24.8 months but it contains 9000 months, which means 750 years. So it will be illogical to plot graph on this scale.

Answer:

x-axis scale, 0–30; label, Months

The absolute value equation that has solutions of 3 and -3 is |x| = 3. Substituting x = 3 or x = -3 into the equation both result in true statements, confirming they are the correct solutions.

Explanation:

The student is asking about solving an absolute value equation that has solutions of 3 and -3. To tackle this problem, you want to set up an equation where the absolute value is equal to both positive and negative 3. The most straightforward equation that satisfies this condition is |x| = 3. This equation means that the solution, x, can be either 3 or -3 because the absolute value of both numbers is 3. To verify that these are the correct solutions, you can substitute them back into the original equation:

For x = 3: |3| = 3, which simplifies to 3 = 3, confirming the solution.

For x = -3: |-3| = 3, which simplifies to 3 = 3, again confirming the solution.

This absolute value equation is an identity because substituting either solution results in a true statement.

Final answer:

Sara paid 55% of the original price of the dress when she bought it for $30. By dividing the sale price by 0.55, we calculate that the original price was approximately $54.55.

Explanation:

To answer the question of what the original cost of Sara's dress was before she saved 45% on the sale, we need to set up a simple percentage calculation. Since Sara saved 45%, this means she paid 55% of the original price (100% - 45% = 55%). The sale price of $30 is what represents this 55%.

To find the original price, we can write the equation:
30 = 0.55 × (original price).

Now we divide the sale price by 0.55 to find the original price:
(original price) = $30 / 0.55 = approximately $54.55.

So the original cost of the dress was approximately $54.55 before the sale.

The original price of the dress is approximately '54.55'

Sara bought a dress on sale for $30 and she saved 45% on the dress

Thus the price she paid for the dress is 100%−45%=55%

Now 55% of the original price of the dress is the amount she paid for the dress

Thus let 'P' be the original price of the dress

We can say that,

55% of P = 30

[tex]55*\frac{P}{100}=30\\ 55*P=30*100\\55*P=3000\\P=\frac{3000}{55}\\ P=54.55[/tex]

Thus '54.55' is the required answer
