Solve, using the Rule of 72 rate = 4%, years = 18, fv=$8,000. Solve for PV. Formula: PV = $1/(1+r) t PV = $8000/(1+.04) 18 PV = $8000/2.0258 3949.03 = $8000/2.20258
18=3(3x-6)
0.5x=18 x=36
x=18
x=18

U can subtract 18 from each side of the equation.
25-7=18 18/3=6
-3
18=3(3x-6)
0.5x=18 x=36
6c-18=4c Why can rearrange this and simplify to 2c=18, which means that c = 9
x - 13 = 5 x = 18
-18
x-18=34 solve for x add 18 both sides x-18+18=34+18 x=52
