Answer:
1.82n
Step-by-step explanation:
We combine like terms to simplify this.
Any variable with no other coefficient can be written with a coefficient of 1. This is because everything can be multiplied by 1 without changing it. This means we have
1n + 1n - 0.18n
Combining like terms, we have
2n - 0.18n = 1.82n
First, subtract both sides by 25:
x^2 - 6x = -25
Because we're completing the square, we subtract both sides by 9:
x^2 - 6x - 9 = -34
(x - 3) = 5.831 (about)
x = 8.831
The answer would be 0.10714 or 3/28 if you wanted to simplify it.
Answer:
The angles are 54 2/3 degrees and 115 1/3 degrees
Step-by-step explanation:
make an equation for the angles x being one angle and y being the other
16+ 2x =y
Supplementary angles add to 180
x + y = 180
Fill in y with the first equation
x + 16 +2x =180
simplify
3x +16 =180
subtract 16 from both sides
3x = 164
divide both sides by 3
x = 54 2/3
Insert the value of x into the first equation then simplify
16 + 2(54 2/3) =y
16 + 109 1/3 =y
115 1/3 =y
