If Emma is 12 Luke is two times her age Kendra is 1 half of Luke's age how old is Kendra
Natali [406]
We already know that Emma is 12, and if Luke is twice her age, then that means we need to multiply 12 by 2, which equals 24. If Kendra is one half of Luke's age, which is 24, then we must divide 24 by 2, which equals 12.
In conclusion, Kendra is 12 years old.

raketka [301]

Answer:

j = 21 and n = 14

Step-by-step explanation:

54j + 3n = 1206

j + 3n = 93

53j = 1113

j = 21

(21)/3 + n = 31

7 + n = 31

n = 14
