In a two digit number, the tens digit is 2 less than the units digit multiplied by three. The reversed number is half the origin
Papessa [141]

Answer:

73

Step-by-step explanation:

Original number: XY

x = 3y - 2

10y + x = (10x + y) / 2 + 1/2

substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2

* 2 both sides and simplify: 26y - 4 = 31y - 19

31y - 26y = -4 + 19

5y = 15

y = 3

x = 7

Original number: 73

if the population of a country increases at a rate of 1.5% annually, and it’s current population is 430,000, how many years will
aleksandrvk [35]
Hi,
a_0=430000\\
a_1=a_0*1.15\\
a_2=a_1*1.15=a_0*1.15^2\\
...\\
a_n=a_0*1.15^n\\

a_n \geq 3*a_0\\

1.15^n \geq 3\\

n*ln(1.15) \geq ln(3)\\

n \geq  \dfrac{ln(3)}{ln(1.15)} \\

n \geq 7.86059688...\\\\

\boxed{n \geq 8}\\
