Answer:
The eldest of them is Brian and he is 24 + 2 = 26 years old.
Step-by-step explanation:
Let
Malachy age = a
Brian age = a + 2
Caroline age = a - 8
Total of their age = a + (a + 2) + (a - 8)
66 = a + (a + 2) + (a - 8)
collect like terms
66 = a + a + 2 + a - 8
66 = a + a + a - 6
3a = 66 + 6
3a = 72
divide both sides by 3
a = 72/3
a = 24
Malachy age is 24 . Caroline is 24 - 8 = 16 years old.
The eldest of them is Brian and he is 24 + 2 = 26 years old.
Answer:
45, 000 J o 45 KJ
Step-by-step explanation:
Recordemos que trabajo realizado = fuerza * distancia
En este caso, fuerza = peso del objeto
Por lo tanto, peso del objeto = 180 Kg * 10ms ^ 2 = 1800 N
Por eso;
Trabajo realizado = 1800 N * 25 m = 45, 000 J o 45 KJ
