Step-by-step explanation:
Let Emma's age be 2x years, then:
Elsa's age is x years, also:
Bella's age is x - 2 years.
In one years time the sum of their ages

k=11
Step-by-step explanation:
3(k - 6) = 15

3/3(k - 6) = 15/3
k - 6 = 5
Add 6 to each side
k-6+6 = 5+6
k = 11
128.309728
add all numbers together and divide by 50(there are 50 numbers)
