Answer:
multiply 0.40 by 150 answer is the percentage so 60
Step-by-step explanation:
Simplifying
2(n + 20) = 110
Reorder the terms:
2(20 + n) = 110
(20 * 2 + n * 2) = 110
(40 + 2n) = 110
Solving
40 + 2n = 110
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-40' to each side of the equation.
40 + -40 + 2n = 110 + -40
Combine like terms: 40 + -40 = 0
0 + 2n = 110 + -40
2n = 110 + -40
Combine like terms: 110 + -40 = 70
2n = 70
Divide each side by '2'.
n = 35
Simplifying
n = 35

The answers are:
Step-by-step explanation:
1)Adjacent
2)Vertical
3)Corresponding
4)None of these
5)1,7 3,5 4,6 2,8 (<--angle numbers)
6)4,5 2,7 (<--angle numbers)
7)1=85, 2=95, 3=85, 4=85
8)1=60, 2=120, 3=60, 4=120
9)1=90, 2=90, 3=90, 4=90
10) No, they are not parallel. A protractor would show that the intersection angles are different, meaning the lines aren't parallel.
