The equation given in the question is
(5x + 2)/2 = 2x - 1
5x + 2 = 2(2x - 1)
5x + 2 = 4x - 2
5x - 4x = - 2 - 2
x = -4
So the value of the unknown variable comes out to be -4. Yes your calculation is correct it seems from the answer that you have given. I hope i have been able to help you in this regard.Only be careful about the cross multiplication part.

The answer is 22.6 ft.
<span>In case you wanna know how to do it, the easiest way for me is I draw like a diagram. So this one's a ramp, so I just drew a simple triangle. It says the distance from the building to the end of the ramp is 22 feet, meaning the base is 22 feet. then the height will be 5 feet, which is the vertical line of the triangle. and you don't know what the last one is, so let's call it c. Here's what your triangle should look like (It's really bad, cuz it's hard to do it on the computer, let's pretend the triangle is much longer and not as steep): </span>
<span>|\ </span>
<span>5 | \ c </span>
<span>|__\ </span>
<span>22</span>
<span>Ok, so you should've heard of pythagorean theorem - a^2 + b^2 = c^2 </span>
<span>a is 5, b is 22 so plug these numbers into the theorem : 5^2 + 22^2 = 509</span>
<span>Since 509 is c SQUARED, you have to find the square root of 509 which is 22.6! There's your answer hope I helped :D</span>
