1.) expand
3x - 15 - 5x = 25 + 6x
2.) simplify
-2x - 15 = 25 + 6x
3.) add 2x to both sides
-15 = 25 + 6x + 2x
4.) simplify
-15 = 25 + 8x
5.) subtract 25 from both sides
-15 - 25 = 8x
6.) simplify -15 - 25 to -40
-40 = 8x
7.) divide both sides by 8
-40/8 = x
8.) x = -5

Step-by-step explanation:
Answer:
The height of the ramp is 1.39 m.
Step-by-step explanation:
We have,
A wheelchair ramp is 8.0 m long
The angle of inclination is 10°
It is required to find the rise of the ramp.
Here, hypotenuse is 8 m and angle of inclination is 10°.
Using trigonometry to find it.
![\sin\theta=\dfrac{x}{8}](https://tex.z-dn.net/?f=%5Csin%5Ctheta%3D%5Cdfrac%7Bx%7D%7B8%7D)
x is rise of the ramp
![x=\sin(8)\times 10\\\\x=1.39\ m](https://tex.z-dn.net/?f=x%3D%5Csin%288%29%5Ctimes%2010%5C%5C%5C%5Cx%3D1.39%5C%20m)
So, the height of the ramp is 1.39 m.
