solve for x 5x2 3x10 solve for y AB yx solve for d APie d22

solve for x: 5x/2 =3x-10

solve for y: A/B = y/x

solve for d: A=Pie (d/2)^2

solve for T: 4RN/d = H/T

Solution

5x/2 =3x-10

5x/2-3x=-10

-x/2=-10

x=20

A/B = y/x

y = Ax/B

A=Pie (d/2)^2

A/Pie=(d/2)^2

(A/Pie)^1/2=d/2

2(A/Pie)^1/2=d

4RN/d = H/T

T=Hd/4RN
