Hurry! solve the equation for the indicated variable. 1. n=m^2-(n+3), for m 2. d-e/3d+e=e, for d 3. q/r-6=q, for r 4. v=4/3(pi)r^3, for r 5. 1/v=1/u+1/f, for u 6. a^2+b^2=c^2, for a 7. s=(pi)rs+(pi)r^2, for s

1.) Take the root of both sides and solve. M=2n+3,-2n+3
2.) Solve the rational equation by combining expression and isolating the variable D. D= 3e/3,-3e/3 Which looks like a fraction. 3e OVER 3.
3.) Move all the TERMS to the left and SET equal to ZERO. Then SET each FACTOR equal to ZERO. r=q/q+ r=q OVER q.
4.) Take the ROOT of both sides and solve. r=3_/6pi^2v/2pi or r=3 to the root of 6 pi^2v OVER 2pi
5.)Solve the rational EQUATION by combining EXPRESSIONS and isolating the VARIABLE u. u=fv/f-v or U=FV OVER F-V like a fraction.
6.) Take the root of both sides and solve. a= (c+b) (c-b) - (c+b) (c-b)
7. Move all TERMS to the left side and SET equal to ZERO. Then SET each FACTOR equal to ZERO. s=-3.14r^2/3.14-1 or S=-3.14r^2 OVER 3.14r-1.
HOPE THIS HELPED!1 IM SORRY FOR TAKING SO LONG! :D

Yes you do, so £1973.09 - £1473.50 = £499.59 so tim overpaid £499.59 .hope this ; )
