Answer:

x = 4

Step-by-step explanation:

The steps we need to take:

1. Simplify left side.

2. Separate the variable and its coefficient from constants

3. Divide both sides by the coefficient to find "x

1) Simplify left side.

5(3x - 4) + 12 = 52

15x - 20 + 12 = 52

15x - 8 = 52

2) Separate the variable and its coefficient from constants by adding 8 to both sides.

15x - 8 + 8 = 52 + 8

15x = 60

3) Divide both sides by the coefficient to find x. (the coefficient is the number that comes before the variable)

15x / 15 = 60 / 15

x = 4

Which of these is equal to ⅔ × ¾ × ⅗?
Sphinxa [80]

Answer:

3/10

Step-by-step explanation:

Just multiply all of the numerators (top numbers)  and then multiple all of the denominators (bottom numbers)

2/3x3/4x3/5  would be 18/60 Then take any number that is a factor to both 18 and 60 and divide both numbers by that factor.  I could use 2 or 3 or 6 because both 18 and 60 is divisible by any of these numbers.  I will choose 3.  I will divide the top and bottom of 18/60 by 3 to get 6/20, now I will divide the top and bottom of that number by 2 to get 3/10

Answer:

We know that the equation of the circle in standard form is equal to <em>(x-h)² + (y-k)² = r²</em> where (h,k) is the center of the circle and r is the radius of the circle.

We have x² + y² + 8x + 22y + 37 = 0, let's get to the standard form :

1 - We first group terms with the same variable :

(x²+8x) + (y²+22y) + 37 = 0

2 - We then move the constant to the opposite side of the equation (don't forget to change the sign !)

(x²+8x) + (y²+22y) = - 37

3 - Do you recall the quadratic identities ? (a+b)² = a² + 2ab + b². Now that's what we are trying to find. We call this process <u><em>"completing the square"</em></u>.

x²+8x = (x²+8x + 4²) - 4² = (x+4)² - 4²

y²+22y = (y²+22y+11²)-11² = (y+11)²-11²

4 - We plug the new values inside our equation :

(x+4)² - 4² + (y+22)² - 11² = -37

(x+4)² + (y+22)² = -37+4²+11²

(x+4)²+(y+22)² = 100

5 - We re-write in standard form :

(x-(-4)²)² + (y - (-22))² = 10²

And now it is easy to identify h and k, h = -4 and k = - 22 and the radius r equal 10. You can now complete the sentence :)

I need help with this question I will give brainliest
guajiro [1.7K]

Answer:

No

Step-by-step explanation:

In order for there to be a right triangle formed, this must satisfy pythagoran's theorm thingy:

a^2+b^2=c^2

7^2+15^2=274

22^2= 484

since 274 isnt equal to 484

There is not a right triangle formed here

1. The three dots at the end of the number is called an ellipsis.
2. Since it doesn't terminate or repeat, the number is an irrational number.
3. When it can be written as a ratio, it is a rational number. 
4. The decimal digits infinitely repeating is called a repeating decimal. 
5. Ending decimal is another word for terminating decimal.
6. The fraction bar in which has numerator above and denominator below is a vinculum. Hope this helps!
