How do I convert 8.41 g/mL to Kg/L
Vlad1618 [11]
Milli(m) = 1/10^3 = 0.001
kilo(k) = 10^3 = 1000
 8.41 * g/ml
= 8.41 g/mL / 1000 mL
= 0.00841 g/L
g = 10^3 * (1/10^3) * g
= (1/10^3) * kg
0.00841 g/L / 1000 g
= 0.00000841 kg/L

Richard and Teo have a combined age of 20. Richard is 2 years older than twice Teo’s age. How old are Richard and Teo?
boyakko [2]

Richard is 14 years old and Teo is 6 years old.

Step-by-step explanation:

Let,

Richard's age = x

Teo's age = y

Combined age = 20 years

According to given statement;

x+y=20    Eqn 1

x = 2y+2  Eqn 2

Putting value of x from Eqn 2 in Eqn 1

(2y+2)+y=20\\2y+2+y=20\\3y=20-2\\3y=18

Dividing both sides by 3

\frac{3y}{3}=\frac{18}{3}\\y=6

Putting y=6 in Eqn 2

x=2(6)+2\\x=12+2\\x=14

Richard is 14 years old and Teo is 6 years old.
