Answer:
Step-by-step explanation:
Did you mean: Change 19/4 into a mixed number (fraction).
How do you turn 19/4 into a mixed number?
As an improper fraction. (numerator larger than denominator): 19/4 = 19/4
As a mixed number (mixed fraction) (a whole number and a proper fraction, of the same sign): 19/4 = 4 3/4
As a decimal number: 19/4 = 4.75.
As a percentage: 19/4 = 475%
3/8+2/5
=15/40+16/40
=31/40
The answer is y=-x+6 because the y-intercept, which is the last number in the equation, runs through 6. It is -x because the slope of the line moves toward the left side, meaning it is a negative slope.

Answer:
![x= 11.47](https://tex.z-dn.net/?f=x%3D%2011.47)
Step-by-step explanation:
By definition the cosine of an angle is the quotient between the side adjacent to the angle and the hypotenuse.
In other words:
![cos (\alpha) = \frac{adjacent}{hypotenuse}](https://tex.z-dn.net/?f=cos%20%28%5Calpha%29%20%3D%20%5Cfrac%7Badjacent%7D%7Bhypotenuse%7D)
In this triangle the length of the side adjacent to the 55 degree angle is x, and the length of the hypotenuse is 20
So:
![cos(55\°) = \frac{x}{20}](https://tex.z-dn.net/?f=cos%2855%5C%C2%B0%29%20%3D%20%5Cfrac%7Bx%7D%7B20%7D)
Now we solve the equation to find the value of x
![x = 20cos(55\°)](https://tex.z-dn.net/?f=x%20%3D%2020cos%2855%5C%C2%B0%29)
Finally
![x= 11.47](https://tex.z-dn.net/?f=x%3D%2011.47)
