Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
so,
x + 12 + 2x - 29 + x + 5 = 180
4x - 12 = 180
4x = 192
x = 48
Simplify
4x-12=180
Add 12 to both sides
4x = 192
Divide both sides by 4
X=48

Hamish buys a new car for 520000
The car depreciates in value by 19% each year.
Work out the value of the car at the end of 3 years.
Give your answer to the nearest $.
Answers
Answer:
$223,600
Step-by-step explanation:
1. Multiply 520000 by 0.19 and get an answer of 98800. This is how much by which the car depreciates every year.
2. Now multiply 98800 by 3 (years). Now your answer would be 296400.
3. Now minus the depreciated value from the original value which is 520000-296400=223600.
Not sure about the answer but I hope this helped a bit
Answer:
$3,567.00
Step-by-step explanation:
Here is how I got it!
First, you will have to borrow the 520,000 from the word problem.
Next, multiply 520,000 with 0.19 with the power of 3
[tex]520,000*0.19^3=n[/tex]
The 3 is the number of years, n is the nearest $ answer.
--
First, do [tex]0.19^3[/tex]
[tex]0.19*0.19*0.19=0.006859[/tex]
(Again, that's a crazy number!)
--
With 0.006859, multiply it with 520,000
[tex]520,000*0.006859=3566.68[/tex]
3566.68 is technically (in money) $3,566.68 (with .68 being sixty-eight cents).
--
Finally, it states to answer to the nearest $.
Just round up the .68 to 1 dollar which will just add one more dollar to 3,566
[tex]3,566.32[/tex] ⇒ [tex]3,567.00[/tex] (since .32 is below .50, you can't round it UP)
Add you $ symbol
With the result being: $3,567.00

Answers
Answer:
JK = 42 , KL = 78
Step-by-step explanation:
JK + KL = JL , substitute values
4x + 6 + 7x + 15 = 129 , that is
11x + 21 = 120 ( subtract 21 from both sides )
11x = 99 ( divide both sides by 11 )
x = 9
Then
JK = 4x + 6 = 4(9) + 6 = 36 + 6 = 42
KL = 7x + 15 = 7(9) + 15 = 63 + 15 = 78

There are 144 people in an audience. The ratio of adults to children is 5 to 3. How many children are in the audience.
Answers
Answer:
In the audience, there are 90 adults and 54 children
Step-by-step explanation:
If we have 5 adults for every 3 children, we would continue this pattern by saying we have 10 adults for every 6 children, 15 adults for every 9 children, and so on.
We can express this situation into an equation by saying 5x + 3x = 144
8x = 144
x = 18
So now we know there are 5(18) = 90 adults for every 3(18) = 54 children
In the audience, there are 90 adults and 54 children

Find the number of minutes Carla runs for each mile. Show your work using mathematics.
Answers
Answer:
Carla ran 0.1 miles per minute.
Step-by-step explanation:
To solve this, we need to use the distance formula.
The formula is d=rt, where d is the distance traveled, r is the rate in which the distance is traveled, and t is the amount of time it took to go that distance. So lets plug it all in.
d=rt
3=(r)(30)
Now, we need to do the inverse of multiplying 30 to both sides, which would be the same as dividing by 30 on both sides.
3/30=(r)(30/30)
0.1=r
The rate is 0.1. Carla ran 0.1 miles per minute.
