Answer: KM =
Answers
Answer:
KM = 4
Step-by-step explanation:
[tex] LM = 3x + 3 [/tex]
[tex] KM = 5x + 4 [/tex]
[tex] KL = 5x + 1 [/tex]
[tex] KL + LM = KM [/tex] (segment addition postulate)
[tex] (5x + 1) + (3x + 3) = 5x + 4 [/tex] (substitution)
Solve for x
[tex] 5x + 1 + 3x + 3 = 5x + 4 [/tex]
Combine like terms
[tex] 8x + 4 = 5x + 4 [/tex]
[tex] 8x + 4 - 4 = 5x + 4 - 4 [/tex]
[tex] 8x = 5x + 0 [/tex]
[tex] 8x - 5x = 0 [/tex]
[tex] 3x = 0 [/tex]
[tex] x = 0 [/tex]
[tex] KM = 5x + 4 [/tex]
Plug in the value of x
[tex] KM = 5(0) + 4 [/tex]
[tex] KM = 0 + 4 = 4 [/tex]

there are 800 seats in the varsity theater. during regular preformances, all seats cost $12 each. It costs the owner $275 to pay his preformers for each show. a: write an expression that could predict the owners profit if "n" people buy tickets for a preformance b: if the profit is $1,213, how many people attend? c: If the same number of people attended but the owner's expenses changed to $375, would the profit increase or decrease and by how much?
Answers
Answer:
The correct answers are the following:
A) P=12n-275
B) 124
C) Decrease by $100
Step-by-step explanation:
A) P=12n-275 - Each person (n) pays $12, then the cost/expense ($275) is subtracted from the income to get the profit.
B) 1,213=12n-275 - Plug in the value for P ($1,213).
1,488=12n - Add $275 to both sides.
124=n - Divide both sides by $12.
n=124 - This the number (n) of people that attended.
C) P=12n-375 - Change the value for expense to $375.
P=12(124)-375 - Plug in the value for n (124).
P=1488-375 - Simplify and find the difference.
P=1,113 - This is your profit.
1,113-1,213=-100 - $100 reduction/decrease of profit (or -$100 to profit)

There are 67 electricians on a jobsite. Thirty-one (31) are "career" helpers. Twenty-four (24) are indentured apprentices. Nine (9) are journeymen. Three (3) are foremen. What percentage of the electricians are indentured apprentices?
Answers
Answer:
35.82 %
Step-by-step explanation:
Total no of electrician job = 67
No. of indentured apprentices = 24
____________________________________
Percentage mean per hundred,
Example for x percentage of any thing
literally it means if there are total no. of 100 things, then x is the number of thing in consideration.
Formula for percentage calculation = (number of a particular thing/ total no of things out of which the particular thing is considered) *100
______________________________________
Here,
Total no of electrician job = 67
No. of indentured apprentices = 24
percentage of indentured apprentices = (Total no of electrician job /No. of indentured apprentices) * 100 = 24/67 *100 = 35.82 %
Thus, there 35.82 % indentured apprentices out of total electricians.
It means that if there were 100 electricians, then there would have been 35.82 indentured apprentices out of those 100 electricians.

A city park is opening a new swimming pool. You can pay a daily entrance fee of $3 or purchase a membership for the 12 week summer season for $82 dollars and pay only $1 per day to swim. How many days would you have to swim to make the membership worthwhile?
Answers
Answer:
41 days
Step-by-step explanation:
The membership would be worthwile if you swim an amount of days paying the daily entrance fee that would make your total cost equal to the cost of the membership. From that you can write the following expression:
3x=82+(1*x), x is the number of days you go to swim
Now, you can solve for x:
3x=82+x
3x-x=82
2x=82
x=82/2
x=41
According to this, the answer is that you would have to swim 41 days to make the membership worthwile.

Point a is at (-1,-9) and point m is at (0.5,-2.5) point m is the midpoint of a and point b what coordinates of point b
Answers
Answer:
B (2, 4)
Step-by-step explanation:
A (-1,-9); M (0.5, -2.5); B (xB, yB)
M is the midpoint of AB, therefore we have these 2 equations:
(*) xA + xB = 2. xM
(**) yA + yB = 2. yM
(*) <=> xB = 2. xM - xA = 2x0.5 - (-1) = 1 + 1 = 2
(**) <=> yB = 2. yM - yA = 2x(-2.5) - (-9) = -5 + 9 = 4
So, B (2, 4)

Answer:
To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.
What value of x makes this equation true? 2x + 3 = 9
Answers
Answer:
the is x would equal to 3
Answer:
[tex]\boxed {\tt x=3}[/tex]
Step-by-step explanation:
We want to solve for x, therefore we must isolate the variable.
We are given the equation:
[tex]2x+3=9[/tex]
3 is being added to 2x. The inverse of addition is subtraction. Subtract 3 from both sides of the equation.
[tex]2x+3-3=9-3[/tex]
[tex]2x=9-3[/tex]
[tex]2x=6[/tex]
x is being multiplied by 2. The inverse of multiplication is division. Divide both sides of the equation by 2.
[tex]\frac{2x}{2} =\frac{6}{2}[/tex]
[tex]x=\frac{6}{2}[/tex]
[tex]x=3[/tex]
Let's check our solution. Plug 3 in for x and solve.
[tex]2x+3=9[/tex]
[tex]2(3)+3=9[/tex]
[tex]6+3=9[/tex]
[tex]9=9[/tex]
This checks out, so we know our solution is correct.
The solution to the equation 2x+3=9 is x=3
A family wants to purchase a house that costs $185,000 . They plan to take out a $135,000 mortgage on the house and put $50,000 as a down payment. The bank informs them that with a 15-year mortgage their monthly payment would be $925.14 and with a 30-year mortgage their monthly payment would be $615.65 . Determine the amount they would save on the cost of the house if they selected the 15-year mortgage rather than the 30-year mortgage. Savings = $
Answers
Answer:
4,592.4
Step-by-step explanation:
925.14×15 = 13,877.1
615.65x30=18,469.5
18,469.5
- 13,877.1
= 4,592.4
Answer:
$55,108.80
Step-by-step explanation:
15 year mortgage
925.14/month times 180 months =
$166,525.20
30 year mortgage
615.65/month times 360 months =
$221,634
$221,634 - $166,525.20 =
$55,108.80
So the difference between the 15 year mortgage and the 30 year mortgage is $55,108.80

Martin has 5/6 of a pizza . Liam has 4 times as much pizza as Martin. How much pizza does Liam has?
Answers
Answer:
10/3 pizzaStep-by-step explanation:
step one:
This problem is focused on ratios and fractions
from the problem statement, Martin has 5/6 pizza
Liam has 4 times more of what Martin have
step two:
so we can express what Liam has as
=(5/6)*4 = 20/6or
=5/6+5/6+5/6+5/6= 20/6
= 20/6
step three:
we can reduce both numerator and denominator
= 10/3
Hence Liam has 10/3 pizza
Quantity of pizza that Liam has is;
3 full pizzas and a third of a pizza.
Martin has 5/6 of a pizza.
Thus;
Quantity of pizza that Martin has = 5/6
Now we are told that Liam has 4 times as much as Liam, then;
Quantity of pizza Liam has = 4(5/6) = 10/3
This translates to 3⅓ pizza
Thus, in conclusion, Liam has 3 full pizzas and a third of a pizza.
