**Please Help. ASAP** Rearrange the formula so the letter in parenthesis is the subject. Show your work as well.

1) v-u/a = t, (v)

2) y-x^2/x = 3z, (y)

3) x+xy = y, (x)

4) x+y = xy, (x)

5) x = y+xy, (x)

6) E = (1/2)mv^2-(1/2)mu^2, (u)

7) (x^2/a^2)-(y^2/b^2) = 1, (y)

8) ay^2 = x^3, (y)

Asimple rankine cycle uses water as the working fluid. the water enters the turbine at 10 mpa and 480c while the condenser operates at 6 kpa. if the turbine has an isentropic efficiency of 80 percent while the pump has an isentropic efficiency of 70 percent determine the thermal efficiency
