find the value of x. then find the angle measures of the polygon
50 points brainliest answer
Answers
Answer: x = 160
Step-by-step explanation:
540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x
540= 100-40+3x = 60+3x
480 = 3x
x = 160
Answer:
0.5x + 0.5x + (x-25) + (x-15) + 100 = 540
x + x - 25 + x - 15 + 100 = 540
3x + 60 = 540
3x = 540 - 60
3x = 480
x = 480/3
x = 160

You have quarters. You find % more quarters in your room. Then you go shopping and spend % of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping. Calculate, in dollars, the amount of money you have left.
Answers
Complete question :
You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters.
A. Write an expression that represents the total number of quarters you take with you when you go shopping.
B. How much money do you have left?
Answer:
[20 + (0.4*20)] = 28 quarters
$3.5
Step-by-step explanation:
Given that:
Initial number of quarters = 20
Quarters in room = 40%
Hence, Numbe of quarters in room = 0.4 * 20 = 8
Total number of quarters taken for shopping :
(Initial amount + Numbe of quarters in room)
(20 + 8) = 28 quarters
50% of quarters was spent on shopping :
0.5 * 28 = 14 quarters
Total left :
28 - 14 = 14
Quarters left in dollars :
1 quarter = 25 cent = 0.25 dollars
14 * $0.25 = $3.5

If 45% of a number is 63 and 35% of the same number is 49, find 80% of that number.
Answers
Answer:
Step-by-step explanation:
1) Let the number be y
45%of y=63
45y/100=63
Y=6300/45
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Let the number be y
35%of y=49
35y/100=49
Y=4900/35
Y=140
So 80%of a number =80y/100
=80×140/100
=112.
Solve for x and y
3x + 2y = 16

A gym charges $8.75 for each swimming class and a one-time registration fee of $12.50. A student paid a total of $56.25. How many swim classes did the student take?
Answers
Answer:
He took 5 swimming classes.
Step-by-step explanation:
The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.
$56.25 - $12.50 = $43.75
Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.
43.75 / 8.75 = 5

Answer:
In arithmetic, variables look like letters.
Step-by-step explanation:
As we know that Mathematical arithmetic deals with numbers and certain properties with them.
Some of the main properties between numbers are as follows:
AdditionSubtractionMultiplicationDivisionVariables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.
For example, let us assume a variable x being equal to 7. so it can written as:
[tex]x = 7[/tex]
Let suppose the value of the variable x=7 changes to x=10, then the new value will be:
[tex]x = 10[/tex]
Therefore, the correct answer is:

A flat-screen television was marked down by 35 percent, which reduced its price by $115.65. What was the original cost of the television before it was marked down?
$214.78
$330.43
$404.78
$4,047.75
Answers
Answer:
B
Step-by-step explanation:
35% of this price is :
35/100 × x = 0.35x
The price reduces by 0.35x.
This equals to 115.65
Now :
0.35x = 115.65
100/35 × 115.65 = 330.43

Is 5/6 equal to 2/3?
Answers
=====================================================
Work Shown:
For now, let's assume they are equal. We'll show a contradiction happens.
5/6 = 2/3
5*3 = 6*2 ... cross multiply
15 = 12 ... here's the contradiction
If the original equation was true, then we would get the same thing on both sides in the final step shown above. However, we get a contradiction, so that means the original equation is false.
Furthermore, the left side is larger in the third step, so the left side is larger for each of the three steps. We can then say
5/6 > 2/3
5*3 > 6*2
15 > 12
Which helps show 5/6 is larger than 2/3.
---------------------
Or you can use a calculator to see that
5/6 = 0.833 approximately
2/3 = 0.667 approximately
which shows the two fractions aren't equal and 5/6 is larger.
Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.
Answers
Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left
