Answer:
36 years
Step-by-step explanation:
Let
x = Elga's age
Alvin's age = x + 7
Sum of their ages = 79
Sum of their ages = Alvin's age + Elga's age
79 = (x + 7) + x
79 = x + 7 + x
79 = 2x + 7
79 - 7 = 2x
72 = 2x
x = 72/2
x = 36
Elga's age = x = 36 years
Alvin's age = x + 7
= 36 + 7
= 43 years

Okie
First find D
In this case it is log x
Now find those terms which are log x, log 2x, log 3x, ….. log 8x
Now add them
You will get log x36 :)
sum = 10000(10000-1)/2
sum = 10000(100001)/2
sum = 100010000/2
sum = 50,005,000
It remains the same. if the shape is the same then so is it's angle measure.
