NO SILLY ANSWERS!
Answer:

Step-by-step explanation:
(4x-8)+36 = 180
4x - 8+36 = 180
4x +28 = 180
4x = 180-28
4x = 152
x = 152/4

Please Help. If m ∠ EJF=56, find m ∠ FHK.
Answer: 124 degrees
========================================================
Explanation:
If we assume these two things:
JC parallel to KDJA parallel to HBThen this would allow us to say that angle EJF = angle FHG because they are corresponding angles.
So that means angle FHG = 56
This then leads to:
angle FHK = 180 - (angle FHG) = 180 - 56 = 124 degrees
I subtract 14 from a certain number I multiply the result by 3 the final answer is 3 what was the number
Answer:
15.
Step-by-step explanation:
3(x - 14) = 3
3x - 42 = 3
3x = 42 + 3 = 45
x = 15.
Let the number = x
Set up the equation:
3(x-14) = 3
Simplify:
3x -42 = 3
Add 42 to both sides
3x = 45
Divide both sides by3
X = 15
The number is 15

f(x)=x^2+12x+34
Answer:
(-6, -2)
Step-by-step explanation:
[tex]f(x) = {x}^{2} + 12x + 34[/tex]
[tex] = f(x) = {1x}^{2} + 12x + 34[/tex]
= a = 1, b = 12
[tex] = x = - \frac{12}{2 \times 1} [/tex]
[tex] = x = - \frac{12}{2} [/tex]
= x = -6
[tex] = f(x) = {x}^{2} + 12x + 34.. = - 6[/tex]
[tex] = f( - 6) = - 2[/tex]
= (-6, -2)

[tex]15x-6+x-3 = 39[/tex]
[tex] 16x-9= 39[/tex]

Hope it is helpful.....Answer:
x = 3
Step-by-step explanation:
Given
- 3(- 5x + 2) + x - 3 = 39 ← distribute parenthesis and simplify left side
15x - 6 + x - 3 = 39
16x - 9 = 39 ( add 9 to both sides )
16x = 48 ( divide both sides by 16 )
x = 3

Find the area of the following quadrilateral.
Answer: 480
Step-by-step explanation:
The quadrilateral ABCD is a trapezium
The formula for area of trapezium is
Area of trapezium = 1/2 × (parallel side 1 + parallel side 2) × h
So we can place the given values into the formula.
We get
Area = 1/2 × (9+15) × 40
Area = 1/2 × 24 × 40
By multiplying all of them we get
Area = 480cm

an agent gets a commission of Rs 500 on the sales which amount to Rs 5000 how much will the businessman get from the sales
Step-by-step explanation:
Since commission the commission and is already given then the total sales the businessman gets;Total sales
Rs 5000- Rs 500= Rs 4500
The required amount received by the businessmen is 4500, from the sale.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the money businessman get be x,
According to the question,
x + commission of the agent = 5000
x + 500 = 5000
x = 4500
Thus, the required amount received by the businessmen is 4500.

Write 2.71 as a simplified fraction.
Answer:
[tex] \frac{271}{100} [/tex]
Step-by-step explanation:
hopefully it makes sense
:)
The decimal 2.71 can be written as the simplified fraction as 271/100.
What are Fractions?Fractions are type of numbers which are written in the form p/q, which implies that p parts in a whole of q.
Here p, called the numerator and q, called the denominator, are real numbers.
The given number is 2.71.
We can write 2.71 as 2.71 / 1, since any number divided by 1 is the number itself.
Multiplying both numerator and denominator of 2.71 / 1 with 100, we get,
(2.71 × 100) / (1 × 100)
= 271/100
This cannot be simplified further since 271 is a prime number.
Hence the simplified fractional form of 2.71 is 271/100.

Answer:
here you go :)
Step-by-step explanation:
You can approach this problem by thinking about going in the opposite of the directions indicated starting at the point (3, 4).
If you ended at an x-coordinate of 3 after having moved 4 to the left, then you can start at 3 and move 4 to the right to see what x -coordinate you started at: 3 + 4 = 7
The x coordinate of the STARTING point would have been 7.
You can do the same with the y-coordinate: start at 4 and travel down 1 unit. The y-coordinate of the STARTING point would be 3.
Therefore, the coordinates of the starting point would have been (7,3)
