1/3n + 5 = 9. N equals twelve. This is because you subtract five from both sides of the equation to get one third n equals four. Then multiply both sides by three to get n equals four.

Answer:

1/3x + 5 = 9

x = 12

Step-by-step explanation:

If x is the number...

1/3x + 5 = 9

1/3x + 5 - 5 = 9 - 5

1/3x = 4

(3/1) 1/3x = 4 (3/1)

x = 12

14(0.89)^x+4.5 =162

lisabon 2012 [21]

$14(0.89)^{x + 4.5} = 162$
$\frac{14(0.89)^{x + 4.5}}{14} = \frac{162}{14}$
$0.89^{x + 4.5} = 11\frac{4}{7}$
$ln(0.89^{x + 4.5}) = ln(11\frac{4}{7})$
$(x + 4.5)ln(0.89) = ln(11\frac{4}{7})$
$\frac{(x + 4.5)ln(0.89)}{ln(0.89)} = \frac{ln(11\frac{4}{7})}{ln(0.89)}$
$x + 4.5 = -2101.14032500$
$x = 2105.64032500$
