Answer:
(4z)/(3m)
Step-by-step explanation:
To start, let's get rid of the 3/4 by multiplying everything by 4/3 and getting 4/3. Now, we have 4z/3 = mn, and we can just divide both sides by m to get (4z)/(3m).

Normally you need 1 foot run per 1 inch rise so to rise 36" you need a 36 foot ramp. If you want to start the ramp 12 feet from the porch you will need to do a switch back -- that is, zig zag the ramp so as to get 36 feet in length.

Answer:
x=100
Step-by-step explanation:
Simplify -4/5x-3/20x+1/4x
-7x/10=-70
Multiply both sides of the equation by -10/7.
-10/7*(-7x/10)=-10/7*-70
Simplify both of the equation.
x=100
