Answer:
![x=11](https://tex.z-dn.net/?f=x%3D11)
Step-by-step explanation:
So we have the equation:
![12x-39=8x+5](https://tex.z-dn.net/?f=12x-39%3D8x%2B5)
First, subtract 8x from both sides:
![4x-39=5](https://tex.z-dn.net/?f=4x-39%3D5)
Add 39 to both sides:
![4x=44](https://tex.z-dn.net/?f=4x%3D44)
Divide both sides by 4:
![x=11](https://tex.z-dn.net/?f=x%3D11)
And we're done!

Step-by-step explanation:
Answer:
A =5407.865 in ^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi *r
260.62 = 2 * 3.14 *r
260.62 =6.28r
Divide each side by 6.28
260.62/6.28 = r
41.5 = r
To find the area, use
A = pi r^2
A = 3.14 (41.5) ^2
A =5407.865 in ^2
Answer:
We know Cot51 = x/17
=> 0.809784 × 17 = x
=> 13.753 = ×
.°. The value of x = 13.753 ~~ 14.000 (Ans)
Answer:
-5x + 11
Step-by-step explanation:
All you're doing is substituting.
f(x)=-2x+3
f(1-x) = 2(1-x)+3
= 2 - 2x +3
= -2x + 5
g(x)=3x+3
g(1-x) = 3(1-x)+3
= 3 - 3x + 3
= -3x + 6
Now add them together and combine like terms:
f(1-x) + g(1-x)
-2x + 5 + -3x + 6
= -5x + 11
