So you know that all the angles in a triangle must add up to 180. Therefore, you can make this equation:
[tex](-20x+3)+(-40x+18)+(-15x+9)=180[/tex]
And now just solve for x!
[tex]-75x+30=180\\-75x=160\\x=\frac{160}{-75}\\x=-2.4[/tex]
So, your answer is:
x = -2.4
X = -2.4

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 3 to 2 if there were 4440 total votes how many yes votes were there
Answers
Answer:
Y / N = 3 / 2
N + Y = 4440
Since Y = 3/2 N
3/2 N + N = 4440
5/2 N = 4440
N = 8880 / 5 = 1776
Y = 1776 * 3 / 2 = 2664
1776 + 2664 = 4440
2664 / 1776 = 3 / 2

if f(x)=3x-1 and g(x)=x+2,find (f+g)(x)
Answers
Answer:
(f + g)(x) = 4x + 1
Step-by-step explanation:
Given f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x):
We can rewrite (f + g)(x) as f(x) + g(x), and solve the composite functions through addition:
f(x) + g(x) = (3x - 1) + (x + 2)
Combine like terms:
f(x) + g(x) = 3x + x + 2 - 1 = 4x + 1
Therefore, (f + g)(x) = 4x + 1.
